Yep, I run SA Elites on my brevet bike and have had zero issues in 20+ years.

While descending a very steep hill at 50+mph in France in '91 I had to grab a few handfuls of brake lever to panic stop for a red light (blowing it would have been fatal). I managed a text book, controlled stop at the signal. The guys I was riding with caught up and one asked "Who burned a clutch?" I said "Watch this" and spit on my front hub. The 'sizzle' was telling of how hot they can get.
