I too would like to be more consistent. I have arrived at the conclusion that any problems I am having are not equipment related. Any inconsistency is brain-related in my case.[&:]
I can suggest two books. " Advanced Archer, How to Stay Calm at Center" is a great book for training your mind. I have read it a few times, the only problem being that it can relax you to the point of falling asleep.
I am currently reading Bernie Pellerite' s book " Idiot Proof Archery." Like the first book, it does stress the importance of shooting more or less subconsciously, and only concentrating on aiming. It is also a better book than Advanced Archer in terms of acutal archery shooting form, etc.
I am guessing that your bad days are happening when your conscious mind is trying to control more than one thing at a time, which it can' t do. " Zen in the Art of Archery" stesses the role of the subconscious, but in a round-about kind of way.
The subconscious is where it' s at for consistent shooting. When you start to think too much, a bad shot is coming soon!
I' ve got a lot more work to do, but I think I' m headed in the right direction.
Good luck to you Lady Arwen. Hope you are shooting like Legolas soon.
