I needed a tube today so instead of the typical tube I thought something new was in order. The LBS didnt have latex tubes and earlier before they had suggested my trying their particular brand (bontrager) lightweight tubes. I bought one box of lightweights and one box of regular for another app but held them in my hands to get a feel of the difference....and it was substantial.

Now the question: have any of you used or continue to use this type of tube? Have you experienced less durability?
