i posted before about thinking my arrows was making contract with my cables. i change slide adjust slide bar . no contact now . but i can still see my arrows right before they hit the target and they look to be wobbling. heres the thing its real random.i never know when it will do it . i changed over to a rip cord rest this year but it seems to be working fine. the arrows are the same spine i have been shooting for two years set up by the local bow shop . 400 easton epics i am drawing 30 inches at 58 to 60 lbs. any clues ??
