All I can say is, think real hard before moving on with the 3 under approach. I wish I could shoot split finger, but I have shooting 3 under for over 2 years now cause bow is tillered for it, and hard to go back mentally. Most reasons I see for going 3 under is people have a bow too short and they get arrow pinch.

Pick your form and stay with it. Don't do like me and change over and over.
