DH inner tube options.

I’ve no love for big thick stupid inner tubes that weigh a tonne and ruin the handling of my bike, and i don’t fancy no tubes and faffing about with heavy carcass tyres and seam sealant. So i was wondering if any of you DH punters have tried Latex tubes.

I don’t mind having to top them up every couple of rides, i just wondered if anyone had the inside line on what they were like re pinch punctures and if they handled happily with lower pressures.
