UTg is 49/13/2.4 over ~300 hands. Most hands from NL25, NL50 hands show him at 38/7/0.8 over 55 hands, but that could be variance.
SB is 28/18/2.67 over 77 hands. He seemed like a regular to me, but I prolly misread his hand numbers.

I think this is standard. Folding the river would be horrible considering you're getting 4 to 1 with trips and no scare card on the river.
Maybe a slightly bigger bet on the turn.
