Zipp's Tangente Clincher Tires?

Are these tires worth the money. Can anyone give me a short review?

My Hed Jet’s wear them. I feel like they handle great and have good puncture resistance. Came from Michelin Pro3’s prior to these. Would I buy them again, unknown, want to try some GP4000’s next I think.

I have them and like the lot, i used Vittoria CP whatever (their race tires) before. Both are good tires, i would buy the zipps again.
