Interesting. I like it as a gear changer, but it could be expensive.
I generally only like to raise a big draw with position, with the aim of getting a free card. Out of position, if the turn card comes blank, what do you do? Bet out? Check? But with position, you have a chance to either take down the pot when he checks, or check along and get your card for free (even if it does telegraph your hand, assuring that you won't get paid by the dumbest of players when you do hit - but there are usually enough dumb players that will pay to see anyways).
