What if you slip before you’ve got got the PC out? Retrain muscle memory? And also, you’re more likely to have a hesitation when you go handheld mushroom style, as you can clearly see in the video. Just my opinion :)
AMAZING IDEA!! but.. I have no experience whatsoever and I plan to change that very soon, I think this form of deployment will change this sport forever! My only suggestion would be, to give the bridle some "retraction form" feature. Possibly sew in a patch of stretchy fabric. I feel that this will give the bridle a "throw backwards" motion and remove the possibility of failure to not open or strangle the operator.
