About a 2 years ago I bought the Master of the Barebow dvd collection after I got into a shooting slump. I took some pointers from a few of the archers that resembled my style of shooting and took it to the field. I added a few of the tips to my form and sure enough with alot of practice I slowly watching my shots improve each time I shot my bow. Even if you do not agree with all the types of shooting some of the pros on the dvd show you, you will be able to take at least 1 tip from each of them to help you!
I laugh now when one day I can shoot perfectly no matter what I do, then I go out the following day and can barely get my arrows to hit the target! All I can do is go out again and practice some more!
