I am also posting this hear as I am putting a Ritchey 2x9 on a Fisher hardtail. I am going back to a Square Taper Crankset and would like to know what anyone recommends for the Lightest and Stiffest Square Taper BB? Thanks.

The lightest would (I think) be the Phil ti. I haven't noticed any power drain on my current Sugino/Phil combo versus the RF X type setup I had last year. Seems to me this is hype, and that the frame is the more relevant x-factor.
Action Tec Ti BB

Cheap, light and rebuildable...
If you really want stiff: get a BB with a steel spindle. Phil Wood makes one with a lightweight shell, then get the alloy (AL) mounting cups and your set.

Shimano UN-73

Its cheap $20-30, it lasts forevever, its tough. I have 4+ years on mine still running stong and smooth. Only problem is no adjustable will need to know the exact size and shell you need.

the other problem being it's heavy...
At ~250g, maybe the Shimano is a bit pudgy. However, a lightweight Phil Wood Ti spindle BB will weight about 150g and cost about $250! Sure there are cheaper lightweight BB out there, but will they last like the Phil or the Shimano will? Bang for the $, Shimano. Got money in your pocket to burn, Phil Wood.

I didn't know AC made a square taper. I will look in to this.

the AC Ti would be one of the lightest.
i'd go with a un-90 if you can still find one
