I do not know your setup so well but in general I would recommend steering clear of them.
The best my tank ever looked was when the top was loaded with Acro and montipora colonies. The most work I had to put into it was at this same time.
Gradually I found myself doing the kalk reactor, the dual tunze, the oversized ASM, upped the lighting, added the OM device on a closed loop, on line SPS purchases, more money, mo money, etc.
Found myself with my hand in a test kit or in the tank all of the time, battling alk levels, afraid to miss a scheduled water change, not understanding why a colony would turn white virtually overnight.
It all started with me posting a thread, asking what SPS someone would recommend.
It is hard to keep from getting the SPS bug once you introduce them. The CA, especially alkalinity and PH levels become a constant concern for you, as does water quality.
Biggest mistake I ever made but that was me, if you have the time and can keep it smaller, they look great.
If choosing 1, I would do an orange montipora plating type.
Good luck.
