When I first got my ' 02 Patriot, I bought a TT Shakey Hunter to put on it. I had trouble with the bow shooting low so I adjusted the rest to hold the arrow up longer before drop. This made about 6 inches difference in verticle point of impact. My theory was that the arrow point was dropping before the momentum could hold it' s own. Try getting about 4 inches of arrow travel before drop and see if it shoots higher, mine did.
