i would bet tuning issue also. download Eastons tuning guide. thats where that chart came from. to bring it up, lower your nocking point. then to bring them right, move your rest slightly..cant remember what direction i always get confused on that lol. adjust EVER so slightly. hairs at a time.

make sure your spine is good before moving your rest...have someone run it on software...i never got around to buying or id do it for you.

also, offset or helical fletchings will help. your fixed heads AND straight fletchings are both trying to steer your arrow.

and yes...just because you get good tight groups where you aim with field points dont mean diddly squat with broadheads. ive had poorly spined arrows shoot great with fieldpoints. screw on fixed broadheads and go try and find that arrow in the woods. fixed broadheads magnify your errors in setup, tune, spine, form etc...i wouldnt blame the slick tricks just yet...

good luck
