x2 DDave. Being fairly new to trad archry, I've learned what I feel are needed basics for achieving a reasonable degree of proficiency- consistent anchor point, elbow alignment, smooth release, follow through, and intense focus on target. I'm sure there are others some would consider vital, but these are the ones for me. Never gave any thought to grip, i.e. deep hook vs finger pads, sting roll, etc. When I started I just grabbed the string and for me the most natural was a deep hook. Gave no thought whatsoever to string roll. IMHO one's mind can become so cluttered with all these additional considerations that the main purpose of the shot, hitting your target, is compromised. Keep it simple is an excellent bit of advice. And as Dave said, relax and let that natural feeling take over.
