RE: What do I need to start?
The vanes should be cut off for better arrow flight, sounds strange doesn't it? The shots are generally very short, less than 10 yards in most cases and the line paying out the back of the arrow acts to stabilize the tail and arrow flight. That's not to say that you shouldn't try and improve arrow flight by changing the bow, rest, poundageor arrow spine to suit each other but the vanes are more of a detriment than aid.
Bulz, the bushings that you referred to are also available at most larger traditional shops like Three Rivers and Lone Wolf Archery
