well, as I am quiet new to the sport (only 40 jumps) I am still not very good at packing. Currently I am trying to squeeze a Spectre 150 into an Atom 00 D-bag. Technically I am able to get it in the bag, but a lot of times I have to start all over again.
So I was looking for some tips how to pack. Various threads already exist on the topic ( "Getting the canopy into the d-bag" question) and the tip that works best for me is by putting the top of the canopy first into the d-bag.
I guessed that http://www.packingparachutes.com/techniques_tips/greed.htm contained more info about this method.
But unfortunately, I seem to be unable to access the page...
