Hello everybody,
even if this thread is a little bit older I wish to add some thoughts.
In my opinion, there isn't a general problem with extraction forces. If you've ever seen what great constructions these freebag-reserve-combos are then you get the impression that there's not that mutch room for improvements.
But! I still have another concern.
My biggest nightmare ever is a reserve PC trapped into my own burble.
These days, most of the reserve activations are from a low speed malfunction. A huge number of these are the result of an out of control spinner. And there's no problem for the PC to leave the burble, because the PC starts in a horizontal direction. It don't has to fight against gravity and almost immediately catches air. If I remember right, Jump Shack recommends for these reason never to search for a stable belly to earth position after you cut away.
But, when things get nasty you find yourself in a belly to earth position having a AAD fire. And this theems to be a 50/50 thing.
Another example is a 1500ft reserve pull after a missing handle or a hard pull situation. If your PC bounces in the burble then you can get into really serious problems.
Everybody who has ever seen a reserve PC starting on the ground knows that most of them are start a little bit weak. And much of them that are looking powerfull reduce their effectivity radically if you pull the reserve while laying on your belly. Much PCs wouldn't jump more than 2 feet. To be honest: That don't make me feel confident.
The manufacturers deal with this problems mostly in two different ways:
A) Make the PC strong that it will fly out of the burble.
B) Make some kind of balloon (eg Vector PC), so it will move out of the burble.
The problem with both is that I really don't can decide witch concept works better. I often have seen spring loaded PCs wasting their energy by flipping the PC during start and also I've seen much videos where a balloon type PC danced onto the burble.
An interesting question would be, why no manufacturer combines these concepts. And - in my impression - there are some manufacturers that don't go with either of these concepts.
