Goal Line Offense, new ideal

Bifocal is a overload set, placing the fullback behind the strong side gaurd facing the quaterback in a 3 point stance, with the tail back 8 yards deep in the strong side C gap and the WR split out to the weak side. Ola high school (small AA in Arkansas) ran this offense as their base offense. It worked great with running options and powers. Its sorta like playing the 3 shells game, where you have to pick which shell has the the pea under it...but its making linebackers play honest and waiting for the running back come out of the backfeild to decide who has the ball. On most every play the Fullback is runnig right behind the QB, sometimes he gives, sometimes he fakes, and the QB would then open up to a HB dive or run the option. I really want to know if anyone has ran this as a goal line vs a 6-2...it works great against the split 4, if the D-line dosnt shift over to the overload works even better.
