What's not to like? Tyres popping off rims, mid-ride. Sealant spraying over everything. Not being able to get tyres to inflate without special equipment. Limited selection of tyres.
But I'm tired of this rim being a dick so I'll give tubeless a go if it means I don't have to rebuild/sell a wheel.
I drove to london for two weeks and leave again tomorrow. I bring tubeless pump and spare tyre just in case. (Never had to use them)
Your sanity is up for debate anyway. My experience of tubeless tyres is "what's not to like?"
