[25NL-ZOOM] JJ overpair on wet, paired board. Vbet this river?

[Pelion]

I'm just trying out this Zoom thing and still getting used to it.

Villain is pretty unknown after only 10 or so hands. Seems tightish so far. Is this an easy river value bet, or should I consider checking behind? I think most of his range here is missed draws, but the T should hit some of his straight draws, and I guess I should discount 6x since he didn't raise on such a wet board. $6 good?
