Familiarity: I've put it through the wringer
This is a great bb that's super affordable. If you aren't bound by having the most expensive parts on your bike there really isn't that any weight difference between this and the blackbox xx version. Your biggest difference is your bearings, but I have this on three of my bikes and my spouses and they are bullet proof. Never had any issues or complaints. I like the darker anodized look too.
