Hed 3C or Zipp 808 for ITT front wheels

O.K. - here it is - another age old (it seems) debate.

The 808 is marginally lighter, but I can't find any specs that will compare apples to apples on performance of the two - turbulence/drag, etc.

I am looking at both, and asking for your opinions. 3 seconds counts!

For tires - I feel the Continental Podium at about 160 PSI is a great ITT tire - when it's dry! When it's wet - anything BUT this tire!

Help me out guys!

Thanks,

Joel
