so I ordered a pair of schwalbe durano's off of probikekit... about 10 days ago. I've made my payment, and sent them two messages about my order, but received no response from them... not even an email confirmation on the order. I've started a paypal dispute to get my money back. Judging from some of the online reviews of pbk, they really suck at customer service.

Also, kevlar is very stiff. It's not something that's easily stretched. And I have no idea why kevlar would lose strength over time. To my knowledge, that hasn't happened with bullet proof vests or tennis rackets. The reason why kevlar might be discontinued in ropes might be because of its stiffness. It won't be easy to store something like kevlar, because it's not flexible. And I can't imagine it to be very comfortable either.
