    Container comparison

    Something else for you to consider would be your location. Your profile suggests you are located in Sydney. I would be willing to bet that the vast majority of Talons in Australia were built by Parachutes Australia who are conveniently located in Sydney. Of the 3 rigs you mentioned one has local support, just saying....

    Required pull force for main d-bag extraction

    A side note to consider, extraction problem or not, pulling immediately out the door is begging for line twists. Even if you solve your extraction problem you should still consider taking a longer delay to generate the airspeed necessary to lift the bag quicker and cleaner than a 2 second delay will provide. P.S. I jump an RSK 1 and an RSK .5 and have found that overly tight configurations will cause the hesitation you are experiencing. Something I have noticed to be beneficial is to ensure your closing loop is tight, the tighter the better. This will keep the canopy compressed nice a neat inside the container until the pin is extracted at which point the container will relax some making it easier for the bag to lift out.

    Parachutes Australia Airforce reserve TSO or not

    Does anyone out there remember a little thing called "Google"? A quick search turns up this: Seems like a good place to start. The Airforce Reserve is not listed among PAs other TSOs.

    Proper way to seal reserve

    I don't know about "peer reviewed" but there is a long list of credits in the manual the Poynter gives recognition to.

    USA advertising - where?

    You might consider Parachutist or Blue Skies Magazine.

    60" drogue

    I'm confused. You asked for opinions on a big drogue to slow you down with heavy customers. Now you are complaining because you can feel the larger drogue doing its job?

    Why do Tandems have 9-Cell reserves?

    9 cells support the weight better than 7 cell canopies of the same size (due to increased structure) giving them better flight performance and flare power. Also a number of popular tandem reserves were at one point a tandem main before being designated as only a reserve.

    HMA vs Vectran?

    Try using Google. It has lots of answers :-) HMA is High Modulus Aramid. Technora is a brand name of aramid line just like Spectra is a brand name for polyethylene line etc. HMA offers reduced drag due to it being a thinner line than traditional Vectran lines, although some newer designs of Vectran braid are simliar in dimension to comparable HMA lines. Traditionally I would expect Vectran line to outlast HMA although some coated HMA lines are very resilient. It is not that HMA is "prone" to spontaneous failure. It is that once it starts to appear visually worn it's near its end of useful life. Vectran on the other hand can look like crap for a long time before it finally gives up.

    Packing nuances

    Yep. Clearly pocketed and restrictive to deployment.

    Packing nuances

    A little research today revealed that the Vector 2, Talon 2, and Racer manuals all say to rotate the DBag. No pocketed corners in sight on those old things. So the concept clearly pre-dates pocketed corners. The Talon manual even goes as far as to say "FAILURE TO PLACE LINES TO THE BOTTOM OF CONTAINER COULD RESULT IN A PILOTCHUTE IN TOW". So that leads me back to the leverage argument. Of course I could have just made a phone call and asked instead :-)

    Packing nuances

    Absolutely. The correct orientation of the bag gives the PC the advantage of leverage to rotate the bag upright breaking the friction before lifting the bag. I'm not sure this is correct. If it were, Sunpath would greatly prefer bag-grommet-to-reserve-bulkhead/bag-mouth-to-BOC for all its models, including those whose manuals recommend grommet-to-pin. You can't argue with physics :-) Levers have been working for 1000s of years :-) You can of course argue the necessity of that leverage. Can you please link the manuals you are referring to? It may very well be a concession they have made for their own reasoning (the Aurora doesn't count). The Javelin manual on the SP website clearly states "rotate the bag". Another easy way to tell that your DBag isn't meant to be packed grommet to pin is simply the size of the bag in that configuration. Bags are built to fit containers, changing their orientation will mean that the bag dimensions no longer match the container dimensions. If the depth of the bag is greater than the height of the side wall then packing it grommet to pin is obviously not the way it was designed to be packed. Square peg round hole. Edit: As you noted, this has become more of an issue as containers have become more compact with pocketed corners etc. I have also noticed that containers with higher side walls and more rigid boxed in dimensions suffer more here than softer containers with shallow pack trays.

    Packing nuances

    Do not do this. The danger is not that the lines "blow out" of your pack tray. What happens is that your side flaps blow into your pack tray and tangle with the coiled up lines. Lines half hitching around side flaps have resulted in fatalities. So again, do not do this, use some form of line control.

    Packing nuances

    The best reason I was ever given is that on deployment the PC twists the bag into the upright position, breaking the friction of the bag vs container, then begins lifting the bag out of the pack tray. If the bag starts out in an up right position the PC has to break that friction and lift the bag in 1 motion which is obviously more effort for the PC (think shearing forces vs pealing forces). Sure people do it, and sure it works, but it can cause weird deployments in overly tight containers.

    Rafale vs. Freak2 ?

    Sounds pretty intimidating
