After doing a bunch of research and testing friends power meters, I have decided to purchase a Powertap 2.4.
I own both a TT bike and a Road bike. My TT bike has Zipp 606 (404 front and 808 rear) and my road bike has two wheel sets, Zipp 404 and DuraAce 7801.
My thought was to either order the PT with a Zipp 404. My LBS suggested I order the 808. The only racing I do are club and state time trials, no crits or road races, so using the PT on an 808 would be kind of nice, but for everyday use the 404 would be nice.
