Given the Planet X are tubulars and the Zipps with aluminium rim are clinchers - main question will be which tyre type would you prefer to use?

Zipp with the toroidal rim shape (pre Firecrest) if you believe the literature is more aero that the V shaped rims of the Planet X.

Are either of the wheelsets second hand? If so it is worth checking the warranty.

I think the Zipps would be faster. The PX rims don't fair very well in aero tests.

I'm the first to dismiss bike company claims but will admit the advantages of rim shape are very real especially at higher yaw. I ride many windy tt's and will never go back to v shapes (I'm on Heds).

i would search around for some DA50's which you can get for about £800 uk at the moment much better wheels.

PX are good value and are reliable (depending on what hub they have used) can be a handfull in cross winds
Zipp's well i cant think of anything good to say about them. Every wheel i used had problems, from spokes rotating during 16km TT's, hubs failing and rim cracking.
