Too high of a launch angle and spin rate are not good. You'll lose distance, hit more wayward shots, and struggle in the wind.
I recently got fitted for clubs, and part of the fitting equation was reducing my launch angle and spin rate. Both are too high. We worked to control those and also discussed appropriate balls for me. I've always played the ProV1x because I liked the higher launch angle (I had no idea my launch angle was too high).
The fitter suggested using a ProV1 instead. It's made a big difference by cutting down on the sideways misses, making my distances with irons more consistent, and reducing the times I spin the ball back off the green--even as I used my old irons while waiting for my new ones. I'm pretty happy with the ProV1s, but once I run out of ProV1s, I'm planning to do a ball fitting to see what else is out there from other brands.
Like @jlukes said, a ball fitting is important too. Best of luck to you.
