Ditto The Gibblet strings & cables. With the money you save over winners choice you can treat yourself to a new STS and that one item in itself will turn you old bow into a new machine.
I'll be buying one for my 9 year old Mathews soon. I can't wait to slap one on it and see how it does. (incase your wondering I do have one on another bow, so I'm not just passing on others impressions about it)
