Range for calling Flop Raise-all-in

Recent session at the 1/3 tables at the Borgata (AC).

3 young aggressive players have just picked up to go to dinner, taking about 2k off the table.

Villain is of the new players to sit. He is an older gentleman who just kept talking and joking socially. Very comfortable.

We're 100BB effective.

V (300) raises to 15 (within standard opens) from UTG+1.
Folds to Hero (450) with XX in the BB, I raise to 50.
V calls.

Flop(100) Ts 6s 2d

H c-bets 50 for value.
V raises all-in.

$200 for hero to call.

1. As hero, what range are you calling with?
