At first I thought a call was in order but after reading your thought process, I like the raise to ~300. With the weak players behind you it's entirely possible they will call 300 cold. Even if they fold you can call a push from the SB as you are the favorite on the flop with your monster draw.

Another thought I had about this line is that let's say you just flat call and the donks fold. Now if a brick hits and the SB pushes 520 into a 320 pot you don't have the odds to call. However, if you have raised to 300 on the flop and the SB called, the SB is now pushing a 320 stack into a 720 pot and you have the odds to call. Maybe I'm looking at this the wrong way but it seems by raising on the flop you are setting it up so that even in a worst case scenario (the weak players both fold and a blank hits on the turn) you still have the odds to call a SB turn push.

Yes, I am a level 2 on MLG's evolution but damn it I'd like to get to at least a 3.

Edit: fixed some numbers in my pot calculations.
