The hub-cog interface of their track hubs has the same flawed design. I would steer clear of the track hubs for that reason alone.
I have never liked splined cranks for that reason, and have always stayed with traditional square taper and adjustable open bearing BBs. I've seen people at the track have problems with splined cranks on other brands like FSA. As far as splined cogs is concerned, it seems to me that if you have to apply loctite on the lockring to prevent it from loosening, that totally defeats the primary pupose of the splined interface, which is to permit easy and quick gear changes at the track.
