tubeless and no flats?...pure BS, there are internet sites all over the web with people who had flats, which is why everyone recommends carrying a spare tube for tubeless tires, and some recommend carrying 2 tubes. No thank you, I don't want the headache or the expense! I carry spare tube with me now why in the hell would I want to do that with tubeless if supposedly their flat free! Because their NOT flat free. Besides, I haven't had a flat on my primitive tube tires in over 3 years either on my road, mtb, or my touring bike. I can guarantee you that if someone flatted their tubeless, and I flatted my tube tire, I would be up and running before the tubeless person is done.
