I don't play at a high level but it is annoying to think someone else may have an advantage over me simply because of their string. I use Yonex Super 850 Tour Pro yaddayadda (it's got Feel at the top) 16 and it broke today. I like it but it isn't cheap here. In the UK I think we are completely ripped off on strings, and I don't want to buy a 200m reel of something til I've tried a few. Anyway. I hear poly loses tension quicker than multi (?) and I'd rather pop one than lose performance superfast. Am i right in that generalisation? Is my fear of an uneven playing field ungrounded?
