When the sealant comes out of a puncture it makes a rhythmic hiss as the hole passes through the puddle.

The question is do you go fast enough for the fluid to balance the tire like Dyna Beads?

The main issue with road tubeless is it is generally more miss than hit. I work at a bike shop where we install and service a very high volume of tubeless setups on a variety of bikes. A few combinations work great, but a higher percentage of them (enough that I have a hard time recommending road tubeless) have issues. We sell the Continental GP5000 TL tires, and the hype before we got them seemed like they were the answer, but alas, they are hit and miss as well.
Anything above 32-35mm wide seems to work decent but bellow that, you may be in for a headache.

Not sure if he’s talking about a loose fitting tire or maybe a tubeless tire that just won’t mount onto the rim shelf.

My optimistic winter project of taking some used Dura Ace 7850 tubeless compatible clinchers (that had never been set up for tubeless) got sidelined due to the front tire never being able to hold air and leaking large amounts of air through one of the beads. The stubborn tire is a 23mm Hutchinson Atom. I don’t think this tire will ever run tubeless. I mounted and dismounted it like 3 times and caused a small split in the square bead with my tire lever. I need to just wash out the Stan’s sealant and put a latex inner tube in there (for now).

I really like latex inner tubes. I think I have heard of folks putting sealant into their latex tubed tubulars with some success. I’m fairly OK with the daily re-inflation before each ride necessary on my latex tubed road bikes. I did consider injecting about 45 ml of Stan’s in there as an experiment to see if it changes anything.

I've experienced about a dozen flats in the last 3 months, mostly from wire/road debris, although there is some kind of plant around here that produces long (~1") thorns that are hard enough to go through a Marathon+ WITH liners!

The guys at Utah Trikes swear by Flat Attack, and I had them add some to my velo when it was in. I'll give it a couple months, and if it seems to help a lot, I'm going to order a bottle for my other bike as well.

I had mixed experience with their tubes.
The 2" tubes worked well - almost too well as I didn't know I had a nail in my tire until it worked its way to the rim side of the tube - put a hole in there - and the sealant won't help with that.
the ~25mm tubes didn't seem to help seal much at all
The last couple of tubes I bought were defective and blew out within a day of installation (oddly at the same spot).

Bottom line - if you are using the bottle to fill up some mountain bike tubes, it can work great. Just be ware if there is an unusual small loss in pressure day to day - check to see if there is something in your tire. They should hold air with very minimal pressure loss day to day. Enjoy!

I have had 2 wipeouts where I didn't see what happened but at the end the tubeless tire was off the rim; once it was a blowoff (onlookers heard it), the other time, no witnesses, don't know. Once for the front, once for the rear.

I think it's not about the width, it's about the pressure. And since wider tires can run lower pressures, they work better.

Thanks for the heads up. I check my tires (at least) weekly when I top up the pressures.

I've started to carry a Gerber multi-tool with me, as there have now been two instances where there were objects in the tire that I could not pull out with my fingers, and I needed pliers.
