Talked to some Horton guys at shoot Sat w/ same problem. I set your bow up for a friend last fall that shot b-heads 10" low right from field points. Good groups, but low right. Can't find an answer, but Horton's was to go to mechanicals. They included small profile b-heads in package deal. Never did figure it out, as I shoot Excals and don't really care, lol, other than the darn bow beat me.
