So has anyone had problems with front and rear tubliss using stock 690 enduro rims?  Anyone heard of issues?

This just sounds like a logical system versus tubes, specifically on a tire like the Dunlop 606 or 908RR with super stiff sidewalls - I don't want to Replace and Repair those buggers ever again.

I called Tubliss and they really recommended not using their system on our bikes.  Very nice people - the kind of folks you want to give your business.
