Pre-flop, meh. I'd almost rather play the unraised pot with this hand, but it depends.

Post-flop, I don't raise in that spot very often anymore and against some opponents I'll just toss my cards in the muck as-if I just missed the flop.

Yea same. Just call the flop to maintain pot control. You don't want to play an enormous pot with TPGK with a straight/flush draw on the board.
