RE: bow tune ups
How much you shoot is one thing that determines how often you need to tune. Another thing is how radical your setup is. A high energy, hard cam rig HAS to be kept perfectly microtuned to shoot decent. Especially with broadheads. Just like a dragster engine, high performance demands high maintenance.
I shoot a relatively low performance, round wheel bow. When I first got my bow, I microtuned it and made notes about the brace height, axle to axle length, tiller, draw weight, rest centershot and nock set measurements when I got finished. Now, if my shooting starts going sour, all I have to do is press the bow down, twist up my string and cables to get everything back to my baseline measurements and then check the rest and nockset. Shoot a few broadheads to check arrow flight and I' m tuned up again.
I quit messing around with sights and releases and went strictly fingers/barebow. So, I don' t have to worry about loose sight pins, peeps not turning right, string loops stretching and wearing out and all that other stuff. With my heavy arrows, I don' t have to worry much about bushing wear or bent axles. It' s simple and low maintenance. Sure, it means I have to shoot quite a bit to keep in practice but shooting arrows is my favorite hobby. Tuning is NOT on my favorites list.
