I'll put in another vote to flash. Waiting is always a good idea if you're unsure, but personally, I flashed Mighty's rom the same night I got my phone (I wanted 6.5). Since you say you've flashed your TP1 before, you should be alright with flashing the TP2; it's pretty much the same process, except you have to press different button combinations to get into bootloader mode.

Anyway, I suggest Calkulin's 6.5 /Manila 2.1 rom. I flashed it, and even though I'm addicted to flashing, I stayed on that rom for about a month. In fact, the only reason I changed to a new rom was because I just wanted something else; the rom was perfect!

I say go for it; you'll love it!
