I'm a 26 year old 4.0-4.5 level USTA league player that hits with a lot of spin and a rather consistent kick serve. This string is perfect for enhancing the amount of spin while serving. My groundies have excellent topspin and depth into the court. I have Tour Bite 19g strung at 48lbs in my Flexpoint Prestige MPs. Some of the spin I am able to generate turns forehands into backhands in half a second sometimes. Haha. For a poly string, it's one of the more comfortable strings I've ever tried. I'd recommend the thicker gauges or those who are string breakers or those with open string patterns. While stringing- Tour bite does not kink on itself but does have spring memory- so be careful not to get it tangled on your machine. It surprisingly is not as sharp on the edges as Black Widow or Black Seven, which I like. Overall- great string.
