re-raise is right.

Take your fast play and fold equity.

Just remember with pockets to try to call preflop mostly against deep stacks and people who can't let go of top pair / overpairs when your set hits.

They seem to be most profitable:
(a) with 2 mid-deep stacks after a large preflop raise (big pockets)
(b) when a paired board gives you your boat vs. Ax for the set
