I will personally wait. I did installed an scenery and it crashed my system to the point I had to delete it and install it again. Since it is in Beta version wait until they fix the buggy stuff first. When the program become more stable then move on your stuff since a lot of add-owns needs to probably be upgraded to be more compatible with X11. Remember this is the Beta public version even you paid for it, it is being tested and a bunch of bugs are being reported. I will keep x10 if I am you for the next months to come until we have a more stable X11
