Ok, more time with Prince XC. The XC definitely means extra control, because this string has no real power at all. It was very tough for me to find my feel with it. I struggled last night to beat a guy I usually beat 6-2. Some of this was definitely me playing with some questionable footwork, but I just lacked confidence due to not being able to gauge the proper swing speed to use.
On a positive note, it is very very comfortable. It did not even felt like I played tennis at all after that match. Since I have another pack, I will definitely revisit this string, but I also need to check out the new XS that should be out soon. It may be more up my alley.
XC reminds me of B5E - which I do not like for the same reasons.
