Familiarity: I've put it through the wringer
I went tubeless on my mountain bike about 3 years ago, and I have never looked back. I have done about every type of tubeless set ups from using stans rim strips, tubeless rims and even a few "ghetto" tubeless set ups. And Stan's sealant stuff has always been there help fill every little hole and sealing up the bead on those "ghetto" set ups. This stuff is simply the best.
