Bob - I wasn't implying you were not safe, just critiquing the picture!

You asked for the feedback, but just so you know I think you have pretty good form.

Your fingers in the pic seem to be grabbing a lot of string. You can tell this on your release pretty easily. To see what I am talking about place your cursor on the knuckle of your index hand in your photobucket movie clip, and watch where your hand goes when you dump the string. It drops a bit before falling backwards. This may be a result of your elbowdropping slightly, but watching the video gave me the impression that as a strong guy you are using your shoulder and arm a bit more than pulling through the shot with your back muscles. If you either drop the 3rd finger or used it less in holding the weight and really focus on the elbow being pulled straight back on a string with your back muscles you "may" find more consistency.

As I said, this is good form. Watch enough olympicstyleshooters release and you can see some areas that you can try.
