I usually never slowplay sets in this spot either, especially with the flush draw out there. I dont really remember why I did, I think I had a read on my opponents who where really aggro postflop but probably would fold to a raise on the flop. A raise on the turn would announce my hand to the others and let them fold easily - and my position was perfect with an aggro player acting first and probably leading every street and an loose aggro player behind him to call/raise his bets on every street.

In hindsight I would play my hand faster on the flop though, to many scarecards can fall on the turn as you said and I wanted to build a pot. I never said the hand was played good, the river push was the interesting thing about the hand!
