Comments: I never appreciated Wilson and Penn Hardcourt balls until I tried Dunlop Grand Prix. The Penns are slightly softer with a little more touch and the absolute best ball for 1 set. A little different in the second (but hey, I'm not so young anymore and a little "different" in the second set as well). The Wilson does not have the touch, but for weekly leagues I would go with the Wilson, Tourney-time go with the Penn. Cheers!

Comments: This is a well balanced ball, it felt not too light & not too heavy. It felt in between Penn Championship XDs & Wilson US Opens.
