No, because I won't go to the *****mano splined since they aren't using an open standard. When I go splined, I'll go with ISIS. Gives you many more options. In the meantime, I just bought a Raceface tapered BB for my SS. Unlike the disposable *****mano un72 that only lasted 6 months, it's servicable.
Give the big S another year or 2 and they'll come out with a "better" spline pattern that will make their current stuff obsolete.
