Yeah, originally when I started in this hobby I didn't know much about sps, lps, and softies. The Xenia were one of my first corals. But after I saw some sps tanks, I had to make the plunge. While my tank is mainly a sps dominated tank, there are a few softies and LPS. I have no problem with the xenia's unless they are directly touching and sps. In which case the Xenia get a quick slice. But if you want them to spread faster, I would cut them at the top of the stalk, transplant the top to a new location (little flow so they can attach), and then in no time you will have double. Good luck with your tank.
