Beat Bullets?

[Eeegah]

All right, back to basics. Just formed this table, we're at about the third hand or so, thus no reads.

Rrrrrrgh. That's a pretty drawless board for him to check/3-bet on; only thing I could put him on is trips. If he's got 'em I don't come close to having odds to draw to my 2-outer even with implied odds. I still want to peel but I feel like I'm chasing. Should I be letting go at this point? Would a better line have been to cap the flop and muck if he still wants to play at me on the turn (I don't like this line but who knows)?

Edit: 77 is a possibility as well to be sure, but I'd still need to spike an A to win.
