Winner's Choice.... no doubt.
I've used lots of different bowstrings, and installed just about every brand and internet maker around..... and there are two kinds of strings.... WC's and everything else.
Barracuda's are pretty decent for Mathews bows.... although I often replace the lower cable serving outright. My servings are generally better than theirs (sad but true). Winner's Choice has a no serving separation guarentee.... and they are the ONLY strings that I'll keep on a bow of mine for two years. Everything else gets switched out every April 19th (my birthday, during the slow time of year....easy date to remember).
