I used 2 parts Stans to 1 part Slime tubeless (with the rubber bits) for a couple of years with excellent success. Better sealing on larger punctures than the pure Stans. In Moab and St. George, with mostly tiny thorns/cactus, the pure Stans worked fine.
Ultimately, I got tired of the whole deal, and went back to tubes. In thorn and cactus country, Specialized Airlock tubes served me well this past April.
