Good timing & hand behind the ball - revs come almost automatically. And revs are not everything in the game. But if you feel speed-dominant and lack proper ball reaction, working on the release (not revs alone) will be helpful. Proper equipment and layouts will help, too.
Besides: no wrist support recommended. Adds revs, yes, but a crappy release remains a crappy release
Consult a coach, if you want to spend money on the issue.
Good luck!
