bad push?

[chopchoi]

Blinds 25/50, I have about 1500 chips.

I have Q [img]/images/graemlins/diamond.gif[/img]J [img]/images/graemlins/diamond.gif[/img] in the cutoff, and open for 150. The button and both blinds call.

The flop is all rags, with 2 diamonds. It checks around to me; I push.

i figure I have enough outs that I'm not worried, even if I get called, but is might i be better off betting smaller to encourage a call, so I can get paid well if I hit my flush?
