I usually carry a spare Tubliss tube in my pack but I've never used it.
Try them sometime.
Hi Crankshaft - I'm not suggesting they are not a useful alternative to tubes, just saying they are not a [sensible] alternative to mousses, particularly when racing...

The only benefit I can see with using Tubliss is the ability to run other brands of [tubeless] tyres on tubed rims, and the ability to alter the air pressure - both of which have little baring on rally racing - the best tyres for rallying are all designed to run with mousses anyway, and the 15-18psi range of a mousse seems to be the optimum for heavish bikes, hitting stuff at racing speeds - even in sand? So I can't see how Tubliss would offer any benefit?

Ultimately you want to minimise (if not eradicate altogether) the chance of a flat, and an air-inflated tyre can still get holed... yes you can plug it, and reinflate with a gas cylinder, but that all takes time you won't want to lose in the middle of a stage?

With a mousse, it is very rare it would ever go flat (even if it starts to break down with heat, it never goes 'flat') - and if it does start to soften and lose grip on the bead, then the typical trick is to use heavy duty zip-ties to hold the tyre onto the rim for the rest of the stage... straight forward and less than a minute to implement.

I'm not saying Tubliss doesn't have a place, I'm just saying noone [to my knowledge] uses them in rally racing...

ps. That said, Tubliss might have a place in short course sand events or for extreme enduros in muddy conditions, where you might want to run a softer rear tyre?
