I am ambiodextrous. Therefore, I shoot just as well left handed as I do right handed. That being said, here are my weaknesses:
Power break, left handed. Not that I don't get power, but not as much as right handed.
Consistency for Masse'ing to the left when shooting right handed due to bridging. Therefore, I switch to left handed when masse'ing to the left. And vice versa for masse'ing to the right.
As far as other weaknesses, I am not precise on my jump shots. Hitting the OB is no problem, but pocketing the ball and applying CB follow/draw/side spin is very difficult for me.
I also have a weakness on table length (long) steep cut angle shots when the CB is frozen to the opposite rail. My ball pocketing consistency isn't as good as I'd like it to be.
I can't think of any other weaknesses.
BTW: What is your weak side?
