There are winners choice strings and there is everything else.
I have put on plenty of internet maker and offshoot custom or whatever brand on bows.... and in most cases.... within 6 months the owner of the bow will have winners choice on there.
I haven't ever messed with a bow with Mike Carters strings, but I hear that they are on even par with Winners Choice. Vapor Trail didn't impress me a whole lot. Pretty good but no better than Cudas or Hybrids really. They are good if you are on a very very very fixed budget and just absoultly cannot cough up another $25 for whatever reason.
