I don't know anything much about Dr Crane, but there's a few things about Suporn.
Suporn is retiring next year and its very difficult to schedule with him as so many others are trying. There's a lot of competition for cancellations. He's currently training another surgeon to take over (Dr Bank), and there's not a lot of info available about him yet. There's an interview with them if you search for Suporn pdf update.
I believe Suporn wants a one year gap between electrolysis and SRS, and the wait list is over that, barring cancellations. The wait list is kind of frozen at the moment as well, but they occasionally open up new dates in 2019. I assume its due to the changes there and they will open it up properly sometime.
