I have tried both, and have problems with both. 3 under caused bow noise and hand shock, witch drives me nuts Split finger, is what I learned as a kid, causes callous to form on my index finger on the edge of my finger nail, witch hurt like the devil. I figure split should be the easiest fix, but have not figured it out yet. Have tried all types of gloves, and even tabs with leather flaps that protects the fingers from contacting the nock. Any suggestions, on how to prevent getting the callous.
