Pros and Cons of S/H?

[Reeses]

I've been doing a lot of reading on S/H recently, and I'm very intrigued by it. I especially like the aspect that you can't over-water, and I think it would make the watering process a lot easier.

I was wondering if those of you with experience could tell me what you see as being the biggest pros and cons (if any). I know there's an adjustment period and weaker plants might not survive, but I see that as an inherent risk, not a con.

Any insight would be appreciated! I feel like this has the potential to be the future of orchid growing.
