My Giant XTC4 with it's newly fitted Nobby Nics, set up tubeless, just using Gorilla tape and MucOff sealant. They were a bugger to get seated just using a track pump and I had to leave them pumped up with a tube in for a few days to get the tyre stretched to the wheel shape, but once seated and sealed they seem to be holding pressure reasonably well so far. I haven't been far enough to fully evaluate the set up but they felt more supple and grippy than the previous Mibro tyres that were donkeys years old, on my brief test ride.
