I've been doing a lot of noodling around with form trying to achieve more consistency, so I find this discussion very valuable. The biggest challenge for me has been my bow hand - the grips on the two bows I'm shooting now have nothing to provide real consistency, which is a problem for me. Everyone thinks about the draw hand having an anchor point, but to me, there is a bow hand anchor as well, and that's just making sure that you're gripping the bow in exactly the same manner every single time.
This may just be me, but I have found better results from a tighter rather than a looser grip with the bow hand - not a death grip, but firm, not at all like shooting a compound bow. My fiance is three time MT state champion for compound target, so it's always interesting to compare notes on form - and the push-pull method of compound shooting (he isn't really even "holding" the grip at all) is very ineffective for traditional bows. Control of the bow hand seems to be just as important as control of the draw hand for me, where even a slight change in grip can change where the arrow wants to go. I'm thinking of adding something to my grips, maybe two little dots of leather or glue that I can touch with a thumb and a finger to know my hand is in precisely the same place every time.
Anyone else experience this with the bow hand or am I just crazy?
