Thanks all. I'm down too:
Red 22
Sisl2 with spider
Si with spider

I wonder how the standard red (and red rings) will perform well enough - I have read the chain rings aren't that stiff. Don't like the idea of the praxis upgraded rings as I don't want the chain rub even fits in 2 years only. Does anyone else do forged chains that won't rub on red 22 cranks?

Red 22 chain rings are plenty stiff. The only downside is weight - you give up 30-50 grams for the stiffness.

The original red rings were a bit flexy, but that was fixed with the exogram cranksets, which includes red 22. Its hard to beat the price performance ratio if you buy them at readily available street prices.

Hmmm. Does seem hard to compete with the red cranks. The rest of my groupset is 9000. I'm assuming that the red 22 crank gets on well with the 9000 front derailluer ?

Yes, I am using a 6800 front derailleur and it works fine.
