I haven't, but I've heard great things about it.
Lately I've been having fun making thicker streaks (one inch to an inch and a half) in my cast iron pan. I don't know why but I had been wary of using cast iron for the longest time, I think just because I was spooked by the cleanup, but once I got over that fear, it's been smooth sailing. I was extremely happy with how my steak came out on Monday night. But I think the reverse sear would be fun to try and once of these days I'll do that experiment.
With reverse sear you can do thicker steaks, 1.5 being a minimum.
