QQ set, slowplay?

[threei]

$10 +1 sng, QQ in LP, blinds 50-100 stack size t2400
Two limpers, EP stack about same size he is aggressive, raising with some marginal hands pf like A8 off, not as aggressive after flop. Seen him make some bad calls: called an EP raise with 55, after a checked flop called a huge bet from original EP raiser on turn(who had AK and missed) but lost pot to third player. MP limper has small stack around t1300. He is not good, plays crap, calls when he catches small part of flop.
I raise in LP with QQ, make it 300 to go, blinds fold, both limpers call. Flop comes Qs Js X, I think about slow playing here, but decide the pot is big enough to take down right here and bet 700 and they both fold. Do you slow play this and if so how much do you bet on the flop if anything.
