Close between calling and raising. Think I like raising. I'd have to crunch some numbers to be sure but I imagine after raising it's best to call SB's shove.

BTW, the fact that you aren't sure whether you can raise this for value should cause you to think that perhaps you aren't bluff-raising enough in this situation.

Totally true I'm painfully aware i dont bluff this almost ever, what would be good bluff candidates in your opinion ?
(I'm assuming we are calling with a good draw given how small he bets, but maybe i should change this assumption)

Yeah there's no reason why a small bet implies you should call rather than raise with good draws. Nut flush draw is best bluff candidate, along with I guess straight draw with a flush card.
