I use Slick Tricks, 100 grain. They fly absolutely awesome out of my other bows.
I am pulling about 65 pounds on a Jennings bow, a QAD drop away.
For arrows I have tried all that I have, and after finding a small fletching issue recently I am having great luck with practice points.
Arrows I have and tried with this set up:
Easton Axis ST's
Blackhawk carbon Vapors 4000's
Blackhawk carbon vapors 3000's
Easton LightSpeed 400's
The broadheads just seem to be drifting a little bit, and I was curious if there was math involved in finding the shaft I am after.
Redneck, that was very usefull information! I have great confidence in my broadheads, I have lots and they all do the same thing once my arrows are made and tested for wobble. I am using a combination of 4" vanes and 2" Blazers, they all do the same thing.
First we do need more information, Draw length, arrow cut length. @ 62 lbs you can shoot easton 400's if you are between 26" and 28" draw. Also broadheads do have a tendency to plane but using 4" vanes I would think they should fly good if the spine is correct. Ill bet you are more than 28" draw and if that is the case purchase arrows that are correct for your setup and the issue will fix itself very quickly
