I would totally go gruppo if there were one that had all the stuff I would want, but every major track gruppo out there has at least one thing that rubs me the wrong way.

If Phil made headsets, and threw in a Sugion 75 crank, I would buy that gruppo with my fantasy cash.

If Miche made a normal track crank, (do they make a threadless headset?), I would like that.

If Campy and DA made cartridge bearing hubs/bbs, I would like that.

I don't see the point in buying a gruppo if it's not exactly what you want. That's like buying the Kellogg's Variety pack just for the Froot Loops.
