OK, just got an OLD compound bow in a trade (found out it's like an early 80's model that is no longer being made). Now, I've shot a recurve bow before, many, many years ago, but never a compound. Any tips, tricks, etc.? Should I look for anything on the bow that should be replaced, upgraded? Can someone tell me how to use the sights that on the thing? I did a quick search of the interweb but couldn't really find anything usefull, guess I'll have to go to the book store and see what they have. Thanks in advance!
