Good info- rememeber this from the old Easton tuning manual- amazing just how good tht little 32 pager they wrote 20 years ago was!

Centershot, IMO, is quite important. If I need to move my rest much more than 1/16" either way from center, I try different spine arrows. The arrow should go straight down the power path- everyting should be in line- form, and equipment wise.
