I tried Prince Tour XC at 58 lbs on my Tour 98 ESP. I can see why this string is designed for this type of racquet. After 3 hours it still doesn't move and shows no signs of wear. It has very good control, which is in its name. What surprised me most was the comfort. It is much softer than Proline X and it's almost as comfortable as my goto setup, Mono ZX/Marathon at 66 lbs. This string impresses me as the highest "quality" poly I've used to date. The tension maintenance, lack of string movement, durability, and comfort are all at the high end for a poly.
However, I was a bit disappointed in the spin production. I switched to my other racquet with my regular setup, and believe it or not, I get more spin with my ZX/Marathon hybrid. Maybe some of it has to do with me getting used to a new setup, but with Black Shark I noticed big spin production immediately.
So for me, I think the extra spin of a textured poly makes it more appealing than a smooth poly. I'll be trying some of the Volkyl polys from their value pack at some point. For now, the ZX/Marathon hybrid is still my overall favorite.
