Yes, used a rim strip and Stan's sealant.
I have run this exact set up for 2 years, no issues at all. Performs extremely well in mud or on rocky/rooty singletrack.
My rims are "UST" style and that means no need for rim strip. The rim strip is mainly there to cover the spoke holes.
Thanks for the info, I got the Ksyrium elites with stans cyclocross conversion kit and so far so good, two training rides no air loss and easy install. I had the stans ztr 340 comps and couldn't keep spoke tension on non drive side so getting the warranty. The Mavics don't seem as fast but ride quality is insanely better, way more confidence on these.
Good luck with the rest of your seasons.
