I recently got a 30" OB Pro & I like it better than the OB Classic that I was using. It changed the balance of the cue & I like it even better than I did before.
Now it is not the same shaft, 29 vs 30 so there are other characteristic changes but I like the balance difference this 30" shaft put into play.
God Luck with what ever you decide to do.
Best Wishes,
