Arrggghhh. The confusion continues....

Tubeless tubulars?!?!
Went to the website. Seems an interesting solution.
Do I understand correctly the sealant is used ONLY when a puncture flat occurs?
Have you ridden one of these flat or used the sealant repair?

My flats are all puncture flats. No pinch flats. Always some very small pinhole. Tubeless or sealant would probably solve most of my problems.
Should I just try slime?

Will consult with the local LBS.

Thanks to all for the replies.
