I love what U&C is saying because I agree. Strings matter to me in terms of feel and durability, but I adjust when it comes to spin/power and all the rest. If I string at a low tension with full poly I get the ball I want : The same ball if I went a little higher with gut poly. Now the feel and comfort changes, but my game does not.
The main thing for me is price range. So while I consider tour bite the best string out there, does my game drop off much when I drop down to yonex poly tour, or gosen polyon? Not really enough to justify the cost.
