5/10 - Stack-a-donk or Fold?

[PBJaxx]

Pretty basic hand, but I want to hear some opinions.

Villain is ~80/10/1.5 over 35 hands. Small sample, but he obviously sucks at life.

5/10 6-max

MP ($714.25)
Button ($1813)
Hero ($1101.50)
BB ($453)
UTG ($1420)

Preflop: Hero is SB with T[img]/images/graemlins/diamond.gif[/img], T[img]/images/graemlins/spade.gif[/img].
