i personally go $8 here. though that's what i do with my whole range. if these guys know that this is your standard sizing, then nh. although, i think we need to be slightly more barrel-happy when we choose to give them such ridiculous price on the flop. if you're pretty much planning to cbet flop and then shut down on most turns (fwiw i'd definitely be barreling any heart/Q/J) then go bigger on the flop and maximise your fold equity on the one stab you plan to take. if you are confident barreling, and you think there will be a reasonable amount of decent turn cards to do so, then i like the smaller sizing more.
