Which Tyres?

Is the problem with Veloflex clinchers on carbon rims not a thing then ? Veloflex being overly touchy ?

Re tubs rolling vs clincher rims failing - I can't remember many tubs rolling on pro bikes due to heat build up in descending. Beloki was one many years back ? One of the spring arab races this year where the peloton sheltered under a bridge from the heat ?
There was a spate of Sportives banning carbon clinchers a few years back. It may, as you say, be down to riders riding brakes down descents. It may be due to the tech failing under heat build up. Heat build up on Carbon clinchers may even be sorted now - I've not really seen this addressed and confirmed though.

I do have a soft spot for tubs, I enjoy the ritual around the prepping and gluing and the feel of them on the road. However, I'm not entirely convinced in a blind test I could tell the difference between a good cotton/latex tub and a 'open' clincher and latex tube.
Genuine question - Say I wanted to run Veloflex on carbon rims. Are Veloflex's warning on carbon clinchers false, and their clinchers are ok to run on them ? Or should I stick to their tubs on carbon rims
