I Try to keep My Thumb Anchored at the Base of Neck. Thats how I learned with the "Other" Bows, and its worked out so far on My Longbows and 'Curves!! There was an "Old Time Archer" that used to Anchor that way, My "Teacher" told me, but Danged if I can Recall the Mans Name Right Now!!!
As they say "First the Mind, and...." I dont even want to
THINK ABOUTthe Next on the List!! (Hint: Its Why they sell Viagra and Such!!)
EGADS!!!
