The Stan's Sealant is what everyone around here uses. It isn't the least bit slimy or sticky and is easy to use. The reason I use the UST tires is the sidewalls are thicker and stiffer to support the tire with no tube in it. A non-tubeless tire will tend to roll a bit on the rim without a tube in it (it helps support it) and won't handle as well as the stiffer carcass UST.
