The reason I went with Omniums it just because they're easier to install and I already had the tools required. It also helps that it is cheaper than a set of 75s and there isn't the ambiguity about what bb to get.

and chase. I had the FSA K-Force cranks on my roadbike, ridden daily for almost 2 years with no problem what so ever. They're really solid and I just can't see a way of breaking them in anyway. Carbon handlebars on the other hand, well that's another story.
