I have some montis as well.
I have the Leng Sy, Tyree Idaho Grape, Orange Cap, Tyree Atlantis Green with Pink Polyp Cap.
If you want encrusting I hae the rainbow, and the Tyree sunset monti. I also have the setosa but it is not bi enough to frag yet aybe in a month or two.
To get them to stay where I want them I usually just super glue them. Works well for me.
