CycleOps Carbon 65mm vs. zipp 800 + PT

I have Zipp 808 tubular and consider buying CycleOps Powertap G3 Enve Carbon 65 MM.
I don’t find much information about this wheelset.
Can you share some information about it?
Would you consider buying it, or maybe to add PT SL+ to my zipp?

Thanks

They look pretty good. Tour magazine tested the tubular just recently:

They should have that test in English availabe in their next issue on www.tour-qtr.com

Thanks for the information.
Does anyone in the forum has personal experience with CycleOps wheelset?

.

Thinking of buying the same wheels.
I may be wrong but the cycleops is based on the enve 65mm rim front and rear? , not the 67 system in the article (60mm front 70mm rear), though this system also appears avilable as a powertap;

So there appear to be 2 ‘different’ enve powertap wheel choices?

not sure of the pros/cons of the 2 choices, maybe someone else can chime in.

anyone know if the mavic 80 will be released as powertap option?
