By the sounds of this forum, I have a draw length problem...yet I shoot alright and I have a solid anchor point. I had this problem (forearm slap) a few years ago and changed the way I hold the bow. I hold it with an open hand such that my finger tips face the ground (my forearm also faces the ground). I don't smack my arm anymore and my accuracy has increased...but now you folks have me thinking about the draw length thing. Might be something to look in to. Thanks.
