Was my all-in too aggressive? Should I have pushed on the flop?

Realize that once you put in over half your stack on the flop, you're pot commiting yourself no matter what falls, and therefore are slowplaying your TT to an extent. TT's not a strong enough hand to do this, so you might as well push - why charge half price for overcard/flush draws if you're getting all your chips in there against a made hand anyways?

That being said, I think the preflop call is fine, and you have a tough decision to make on the flop. The worse my opponents, the more likely I am to go ahead and push as they like to call with hands worse than mine. I can also see an argument for calling and peeling one off, and judging your next move on the turn action.
