Problem with Wilson regular balls is that dumb guys like me THINK they can hit serves up to 120 mph with them, on hot days, of course. Hot to me is 70 degrees. Of course, I cannot hit anywhere near 120 for real, but the balls bounce so high at the backboard that I think/wish/hope I can serve like in my youth.
For me, normal bounce height on flat first serves with Dunlops are maybe 28-36" high, while using Wilson's, they always bounce 36-46" high at the backboard.
Yes, I KNOW my first serves poke in only around 100.
