Know a couple of people who have/are using them - one had them on test and bought a pair, possibly two? Others have them on their long-distance race bike.
I've been riding wide lightnings like an idiot on my Solaris for 2 years, starting out with putting a nice fat dent in rear rim (too low pressure) and they've been tubeless and trouble free so far.
anyone using or ridden American Classic Wide Lightning wheels? Looking to upgrade my wheelset and these fall nicely into budget and requirements
