After reading the other posts about the wb,  I'm convinced I need one.  Now my question is, can I use it with a overdraw?  I'm not in love with the overdraw but I really don't want to have to buy new arrows either.  Also, I was looking in the keystone bowhunting catalog and was suprised to see they didn't have any overdraws in it at all.  Are overdraws a thing of the past?
