My cousin Steve Levering works at H H Shooting Sports in Oklahoma City.  He actually works in the archery division of that store.  He is hunting now in eastern Kansas on my mom's land but you can call the store at 405-947-3888.  Ask for him and they might let you know when he will get back in Oklahoma.  I think it will be about another week.  He got my son and SIL into archery and he wont steer you wrong.  Mrs. Vogel
