Set vs flopped straight - do you play this any different?

unless there is a big fish in the blinds you were targetting then your preflop raise size is probably too large. you will want to be raising with a pretty wide range on the BU to steal the blinds so your button opening range will benefit from a smaller "standard" opening size. flop is played fine.

The question is did you thought of all these ranges after the hand of during? Don't stare blind on ranges to much, in my experience people just tend to things differently, randomly, especially a fish.
