RE: What are your thoughts?
I have a bow that is wearing Winner's Choice and I wouldn't say they they are the best. They are very good and very expensive. Unlike some people I base my opinion on the fact that I have tried a few others for comparison and really have no brand loyalty. Nobody can say what is BEST unless they've tried them all and that's is totally impossible.
I have used H&M, Prostrings, and Bucknasty and any of these are the equal of Winner's Choice in my opinion. I think Bucknasty strings might have a slight edge, but it's really hard to differenciate between any of them as for quality of workmanship. MeanV on here deals Vapor Trail, which have a faithful following.
That being said, you have a shop that apparently deals with Winner's Choice. Is getting another brand going to jeopardize a relationship? If no then compare prices and pick one. You really can't go wrong with any of them.
And the few I have mentioned is just the tip of the iceberg, so to speak.
