Yep, I think I would be calling too. Putting him on AA or 10 10 isn't something I would consider. Hands like Kh Qh are very possible, as are JJ, QQ or KK. It's hard to see anyone re-raising with 55 or 88 so trips seems remote. With an ace in your hand, top pair + top kicker and the nut flush draw, I would shove too
