Last year I made the mistake of leaving my 60" martin x-200 in a warm car strung! I have since than switched to a 58" samick volcano and couldnt get myself grouping consistently. after spending alot of time on this forum checking all the threads I tried the three under approach and BAM!!! GOOD GROUPS!! Tonight I went back out and experimented with both split and 3 under and was still feeling a little unsure of the 3 under so I raised my anchor point from my jaw to my cheekbone with split finger and now my arrows are touching at 10 yards thanks to everyone! cant wait to try it at a further distance.
