I have sighting problem of my own. I' m using a 5 pin trophy ridge flatliner and a c-peep. I' m shooting @ 257fps and I can' t get enough elevation to shoot past 30 yds. Even at 30 I' m about 4-6" low. My flatliner is so low trying to get my elevation that my vanes are only clearing the fiber optic lines by 1/2" .

2002 Hoyt Ultratec VersaCam 27 1/4" draw@65lbs.
Trophy Ridge Flatliner 5 pin, C-Peep
CE 200 3D select 27 3/4" @359 grns with 100 grn. heads

I' ve tried everything I can think of. I' ve sited for 10, 20, and (tried) for 30, and 40. My bow is accurate, (almost scarily so!) I just want the yardage!
