Another Draw situation

[Dan Rutter]

You are in the SB with a medium Trip hand, like 3 Ts.
UTG folds, CO raises, Button folds, You re-raise, BB folds, CO caps, you call.

So your heads up, and draw two.
CO stands pat.

Is there enough of a chance that the CO is standing pat with two pair, or a lower trips in realtion to the pot size to warrant a check-call? You are getting around 5.5 to 1

This is absent a read I guess, because this situation has not occured with this opponent before and I do not know if he is capable of making a play like this. If I saw him do it before it would change my play more likely to a call. Also, if you would be willing to call, what is the minimum hand you would do so with?
