I'm in a similar boat to you, random.
I'm applying in anesthesiology, and plan to submit on Sept 2nd. I chose to release my Step I scores to programs but will hold the Step 2 scores until I see them, and will release them after I get my eyes on 'em. My thought is that my Step I is not THAT far off of what I perceive some programs will offer me an interview with - so I can take advantage of being the "early bird", and I hope my Step 2 is quite a bit better, so that I can hit the programs that haven't offered me interviews with a "Hey - look what I did" email to update, and hopefully get an interview then. This of course, falls apart, if I do the same or worse on Step 2, but what the hell - they're gonna see my scores someday anyways.
If your Step 1 is in the interview cutoff range for the specialty you're choosing, why not send those scores out, and see what kinda interviews you get?
Either way, good luck!
