I don't recall if any poly user mentioned this but the set I used a couple of years ago were nice- not too stiff, good both arco and plzz. The reason I went back to Evahs was that the polys were chewing up my fingerboard in a rather alarming way. They didn't feel that rough while playing but I'd never had a set of strings that left that sort of string marks. Of all the strings I've tried over the years, Evahs work the best for me.
