Well, it's like this...my modern firearm friends think I'm odd to be shooting BP anyway. My thinking is that, sure, I'll probably get teh wack put on me first during the zombie apocalypse but I'll look heck of a lot cooler than they will. The twist draw...icing on the cake.
Seriously though, I think there is some argument that it is as natural, if not more, than a "standard" draw. Put your arms out in front of you a ways with your elbows bent. Let your wrists hang loose. If you lower your arms, you're in a rather natural position for a twist draw. If you try a standard draw, you must cock your wrists and hyper extend them. This tension might...MIGHT...slow you down. Aren't fast draw holsters modified to put the gun at a different angle for quickly, more relaxed draw. My Wing Chun experience teaches me to loook for a more relaxed way of doing things.
Additionally, butts forward allow you to do same-side twist draw or crossdraw. Strong side with butts to the rear only allow for same side draw. So, butts forward is more versatile.
Your thoughts are appreciated.
