  1. I feel it's the right question, wrongly worded. As others have already talked about, it's a tool to gauge the experience of people when jumping together with them, which is vital for a load organiser to ensure a safe and fun jump. However, if an FS organiser asks that question to me, the answer is 1300-ish. That won't help him, since only about 100 of those were actual FS jumps. So the better question would be to ask what one's experience is, what they have done before, which positions, etc. Any good load organiser will quickly be able to determine what jump is safe and fun after that. And good load organisers will not look down on anyone for having a particular (typically low) amount of experience, only the shitty assholes will do that. Seek out the cool load organisers, avoid the shitty assholes.
  2. Have you tried contacting Thomas Sports directly? http://www.thomas-sports.com/ As far as I know they are still operational.
  3. Fair enough, but I'm not sure that this route is the correct one to solving the problem of hard openings. Part of the success of the three-ring system (and why it superseded pretty much any other release system ever thought out) is that it is highly reliable. For skydiving equipment, reliability is a very big concern. As already mentioned, a drogue system adds quite a few failure modes which may make it too unreliable to be worth it. In practical terms: I see more instances of tandems having drogue issues than I see instances of hard openings. The slider already does a very good job of slowing down ram-air canopy openings. It's quite fun (in a slightly morbid way) to take a look at all the ways people tried to slow down ram-air canopy openings prior to the slider. My personal guess would be that an incremental improvement on the slider could very well be better in terms of reliability, with the same effect on reducing hard openings.
  4. This part of your post makes me think you might be jumping Ravens (or Super Raven). Although any canopy design is theoretically capable of painfully hard openings, the Ravens have a reputation of also being practically capable for it. If you have actual experience with painful openings on one of those canopies, I would suggest you first look into switching to another canopy type that is known for softer openings, before walking the difficult and laborious path of building a drogue system on a sport rig, or the slightly less difficult path of messing around with slider sizes.
  5. Agree, but for the example of a Sabre2 190, I think that the difference in performance is not noticeable to anyone but an experienced and attentive canopy pilot. And almost certainly it is inconsequential to the type of flying that's typically done with a Sabre2 190. And in theory, any canopy can be relined with Dacron lines. Some manufacturers won't offer a replacement dacron lineset for some types of canopy, but if you still insist on dacron lines, any Rigger worth the title can cook one up from a stock roll of dacron. It's a lot more work than the pre-made manufacturer replacement linesets though, so likely a lot more expensive too.
  6. Regulations will likely be highly variable depending on the country. In practical matters, a balloon jump requires a willing balloon pilot and a fair amount of experience by the jumper. If you get scared by the idea of landing off in a field that looks grassy from above, balloon jumps are NOT recommended. Assume you land somewhere that you haven't seen from the ground before, assume the landing field is small, assume there won't be much wind on landing (since balloons only fly in calm conditions). If none of that scares you, and if you have enough experience to jump and land confidently in whatever field, I can highly recommend balloon jumps. I've made two of them in my 1300 jump career so far, and both easily rank within my top-10 jumps.
  7. Regarding the bigway record: there's always rumours, but nothing serious has reached my ear. I would image a serious attempt is going to require a multi-year plan with build-up of the bigway skills for the current jumpers. Most of the bigway stuff that I've seen and been involved in during the past couple of years was more recreational-style, having fun and playing around with formations up to 50-ways, but more typically smaller than 36-ways. And there was some stuff going on in the multi-point bigway records and night bigway records last years.
  8. If you have not yet done the basic ground course, there's pretty much nothing you can meaningfully train at home. You need the ground course to know how to do many things properly, then you can practice those at home. If you try stuff before the ground course, it is likely that you'll have to unlearn it later on. And yep, it sucks that all the DZs in the Netherlands are closed right now... Nothing to do but wait.
  9. I agree that this should ideally be DZ in-person stuff, but some people are not fortunate enough to have knowledgable people nearby that they can lubricate with a drink for learning this kind of stuff. And you got me interested, what kind of monster requires 16 risers?!
  10. Usually, this can be found on the manufacturer website. Different manufacturers have different requirements (sometimes none at all). There's a talk on youtube by a British rigger that talks more about this, intermeshed with other stuff regarding inspections etc. I have never heard of reserve canopy lifetime being limited or dictated by actual flight time though, only based on amount of activations and/or repacks and/or age.
  11. Terrible openings and constant line twists are not necessarily a result of the canopy type. They may also occur when the canopy hits a certain age, and especially when the lines hit a certain age. Most line types (especially microline, which is commonly found on a Sabre2) will exhibit some sort of shrink. This affects the line trim, which in turn affects (usually negatively) the openings of a canopy. With smallish canopies (~135 and below) those effects can easily happen after only ~300 jumps on the lineset. Microline will typically still look perfectly fine at that age, so just looking at the wear & tear on the lines isn't enough to determine if the lines are still good.
  12. When I bought a secondhand camera helmet, it had a poor man's sight on it. A round piece of coloured plastic with a hole in the middle, on a peg bolted on the helmet. No articulation or other fancy stuff, something like this: http://www.chutingstar.com/camera/skydive-video-gear/ringsights/tinted-eyesight-assembly At least a lot cheaper than all the newton ring or otherwise fancy optics, and it worked perfectly fine for me.
  13. Or even better if they've forgotten that we want to get out 3 km prior due to doing CRW with hardly any uppers. Jackpot is if they climb out right after us. Have fun hiking back! ^_^
  14. About as well as I can (or want to) hear "Door!" while on jumprun.
  15. That's why I like my €0,15/pair high-end foam earplugs (3M earsoft FX or Moldex Spark Plugs). Plenty good enough protection, and zero worries if I lose one. Sure, there's no super-fancy frequency-dependent attenuation to hear speech more easily, but we aren't holding deep philosophical discussions anyway while skydiving.
