i am a tubeless advocate. don't let all the naysayers dissuade you, I found it simple to set up, easy to maintain, and only 1 flat in several thousand miles. the flat was a drywall screw entering in the tread area, through tire, and out a second hole in sidewall. If I had more than one C02 cartridge I could have sealed it up and limped home. I always carry a tube with me for the slight possibility that there is a puncture that will not seal. I think that you should choose a tubeless ready tire, but most rims can be converted to tubeless with rim tape, or even a strip of gorilla tape. I have toured tubeless, trained tubeless and run tubeless 700x25c tire on my road bike, they offer lower rolling resistance with much more comfort and traction with unparalleled flat protection. you will always find curmudgeons who hate/fear change and will make you think things will bring the end of the world, give it a try and be patient and you will be rewarded.
