I generally try to move the arrow rest and nocking point, first to geta good paper tune, and then to get fixed BH's and field points hitting the same. This is outlined very well in Easton's Tuning Guide. I have done pretty well in this endeavor with the various Hoyt bows I have had in the past. Just make sure you start with a properly spined arrow and no contact issues.

Got a Mathews recently and can't quite get the two impacts the same. Close, but maybe inch and half horizontal difference in group centers.
