The Stans Crest have been great and a doddle to set up tubeless - 1 wrap of Stans rim tape, fitted the tyres by hand (no levers) and they inflated straight away with no sealant. Added some sealant and they took a day or two to stop leaking and been great since. Did a long group ride at weekend with some steep muddy pitches - only me and my mate riding 29ers could get up them, those on 26ers were walking. The big wheels and better traction from softer, tubeless tyres means I can ride up trails that have defeated me for 20 years.
