I was actually going to start a thread regarding this...
After initially shooting 3 split I switched to 3 under and saw considerable improvement. Just tonight (after reading another thread here) I tried 2 under and I'm LOVING IT!!!
With 2 under I feel like I'm lining everything up better, I'm getting a quicker, more consistent anchor, a cleaner release and less torque. For me it just seems to fit. I only wish I had tried it sooner.
I tried 2 split also, but as with 3 split I get alot of pinch and can't line up the shot and my anchor. That's just me.
Now I'm gonna go ice my middle finger...pretty numb right now.
