Leatherneck,
I do the same thing. I shoot split finger, tab.
Only happens when I'm shooting close range, eyes closed (working on my form - reaching my anchor - feeling the shot.)
Anyway, the string is hitting my lip. Happens when I shoot my cordovan tab. I switch to my hair tab, doesn't happen. ?? Also, it doesn't happen when I'm shooting normal (eyes open).
I think that I'm probably tilting/turning my head too much into the arrow. I would like to video myself, but don't have a cam.
