Hey there Ocho,
I dont think you are 100 percent correct in your statement regarding vol impact on Butterflys..
Intuitively, when you have butterflys that are far out if the money,it would make sense that you would need a pop in vol to have them increase in value as higher vol would imply a gretater likelyhood of possibly getting there..makes sense??
Obviously if you are long the ATM Bfly,you would like the vol to go as low as possible so the likelyhood of the stock glued to the short strike increases..
Compare ATM flys vs way OTM and you will see what i mean
