Josh, I totally understand what you are saying, and I am not disagreeing with you. But the point I was trying to make to Jim, was that worrying about pinch flats should not be a reason to go tubeless. Unless you are riding across sharp rocks, or jumping off 10 ft. drops, or hitting gnarly roots at warp speed, pinch flats are just not an issue. I have not ridden the trails in Virginia where Jim rides....maybe he rides in some way gnarlier stuff than I do.
OTOH, if Jim wants to go tubeless, then do it for the performance benefits that you are talking about. It sounds like the process is easy with the new UST wheels that he has. If it improves the ride, then by all means go for it.
One of these days, when I wear out my present Slant Six tires (which are not sealant friendly, according to Kenda), I will get some UST or sealant-compatible tires and try tubeless too, as my rims are tubeless ready. In the meantime, if, as you say, ignorance is bliss, then I must be very ignorant, because I am having a great time on my bike this year. That machine is just humming a sweet tune lately, and I am having no trouble navigating the single track in our local woods.
BTW, I just put a new flat, wider handlebar on the Paragon and had my first ride with it tonight. Great improvement in handling. I can really grab the bike by the scruff now and make it do anything I want. Between that and the new tires I put on last autumn, I've finally got it handling like an agile 26er. Love it!
