Last season i went with Vapor trial and they were about 85$ installed, they seem to work pretty good.
It's been 3yrs or so, Landon. But I think I paid $100 ($10 of that was installation....because I didn't buy the bow from my shop).
Cant help you with Winners Choice but incase you decide on something different, check out H & M bowstrings. Great prices and great strings. http://www.hmbowstrings.com/products.html
I currently have a special on VaporTrail strings and Cables including clear Halo serving. If interested you can send a PM. Dan
YOWZA!!!!!!!!!! Thats some serious CA$H... mine back up string cost me $16.50! :D:D........... oh yeah I can install it myself!
