ohio, Some time ago, I posted some pictures of a SUGGESTED bow grip that I find works for ALL grip styles including your C bow. Do a search for a thread here called "grip question" and you will find those photos. See if they help. Yes, catching the bow is NOT a good thing. A wrist strap/sling will work too but really isn't necessary. Also, holding your fingers off the grip adds more tension than is desirable to your bow forearm.
