Bottom Brackets - No Big Whoop?

[msngr]

I poked around a little, but didn't see anything recent about this subject.

For Masters Nationals (US) next year, I was planning to change out any and all spinny parts that use bearings. From what I can tell, there is no compelling reason to get a fancy GXP bottom bracket. Just stick with what is cheap and effective.

Am I right or am I about to be smashed with your superior knowledge and pooh poohed?
