RE: release
I shoot split with a glove. Shot a compound with a tab, don't remember why I switched over, but a tab just feels foreign to me. I shoot split finger, honestly never gave 3-under a fair try. I didn't have anyone to guide me when I started, and never even considered shooting 3-under. By the time I found out some people shoot that way, I was too used to split. Just go with what works better for you.
