Best ISIS Bottom Bracket?????

[Tom boyd]

I want something that is light and durable. Not so worried about the cost.

What are the best 2 or 3 BB's on the market today?

I use the AC ISIS BB. The weight is claimed to be 140grams. Easy changeable (big) bearings.
Also check up FRM CU2-BB ISIS (http://www.frmbike.com/). Even lighter, but the AC might have a stronger axle.
