thanks for the replies.

my poundage isn't too high (i don't think) - ~62# (i'm a pretty big guy) and don't have a physical problem with holding the bow - mental is another question
when I got the bow (last year), the draw was too big and other things were off - got that corrected and shot well - I still shoot well, just get the (what used to be) occassional brain farts. I think I will have the bow checked to see that everything is in order and take a break from shooting. Thanks for the input.
