  1. 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.
  2. 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.
  3. 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?!
  4. 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.
  5. 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.
  6. 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.
  7. 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! ^_^
  8. About as well as I can (or want to) hear "Door!" while on jumprun.
  9. 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.
  10. Agreed, metal hardening is a fairly involved process that requires the full skill, test facilities and QA capabilities of a manufacturer. But TiN treatment is not new, and there are plenty of companies that are skilled enough to do it. It might cost a bit more, but I see no major technical reason why a rig manufacturer cannot buy a batch of TiN hardened reserve pins (likely a pin is defined as a part number with associated drawing and material specifications) and test those for use in their reserve ripcords. As for the grommet, unless I understand the mechanism wrong, a scratched grommet won't cause as much pull force increase as a scratched pin. The scratches in a pin hook into the loop material, meaning you have to physically either pull them out or pull apart the hooked fibres of the loop material. Scratches in the grommet are also obviously not good, since they can cause wear on the loop and/or grab the loop during the opening sequence and delay (or worse) the opening of the reserve container.
  11. Interesting video & discussion. From a materials point of view, I'm not sure that polishing a scratched reserve pin is a good solution, since the material is soft enough that it was able to get scratched in the first place. Polishing it up removes the scratches, but does not remove the ability to be scratched again.
  12. That's why you let a rigger look at it and determine if they are still airworthy. It's an absolute waste to throw away slinks because it's not you but someone else who put 50 jumps on them. A rigger will (should) be able to look beyond jump numbers, and determine if the actual state of the slinks merit replacement.
  13. That's why he was wearing sunglasses!
  14. Lightnings also pack at least a size bigger than equivalent-sized 9-cell normal mains. Plus, there's a whole lot more fun in the air with them ^_^.
  15. If the canopy doesn't already have an attachment point, then it will need some work by a master rigger to create one, especially for jumping it repeatedly. As Lee already said, reserves have some different materials used for fabric, but also for the lines. Typically, they are uncoated (to reduce risk of sticking/tension knots I think), which means they are much more susceptible to damage than normally coated lines. Keep an eye on it, and don't expect to get 500 jumps out of it.
