UPDATE: switched to a drop away rest and am now very conscious of hand torque. I think I have solved the broad head left problem. Only shot a few arrows. Have to wait awhile before shooting again. I messed up my elbow pretty bad at work.
I really like the z7 but the grip is made for 10 year old girls. Wow it's ultra easy to torque the grip even with an open palm. I can palm a basketball, so some modification to the grip may be needed. I've heard of the focus grip but don't know if it will work for me. The bow doesn't seem to be plumb. When I am at full draw, the top of the bow wants to lean to the right(right hand shooter). I have to pay extra attention to the level bubble on the site. This seemed to pay instant dividends. It is not comfortable or natural though. I'm half thinking of a pad of some sort on the left side bottom of the grip. I know this sounds crazy but i'm just kinda voicing it before trying it. Any suggestions?
