Will,
I'm not an expert on grips at all. I was shown this grip at the range and then sent the link by MDBUCKHUNTER which shows the same grip I was shown after we started discussing it.

I used to keep my fingers open except for the pointer fingerand hold the bow in the V of my hand but found I torqued the bow even with that grip. With this grip you'd have to squeeze pretty hard to actually torque the bow by squeezing with your hand. It's actually hard to squeeze and if you do it will cramp the heck out of your hand. i still draw back with my hand open and then go to this grip.

Hopefully, some of the guys on here with a lot more experience than me on this grip can shed some light?
