Using Pokerstove, 65s goes from preflop equity goes from - to + when against 4 to 5 random hands. I think 65s gains the majority of it's equity in these games, though from postflop especially when you're in position. I personally don't think you want to be raising here b/c you are decreasing your implied odds. Plus, you're only showing this hand down maybe 1/5 times so why advertise with it?
