CT vs CTX

Not when you compare a 10-ball to a 10-ball. The number of balls will affect the bearing’s characteristics more than the profile IMO. Sure, there are obvious physical differences in the shape and people will say “the flat part of the CTX allows more string layers without bunching”. You just wait for it. But it’s bull. You won’t notice a difference.

On a sleeper without doing ANY tricks at all, the CTX will precess more often. That’s it. And who wants to just watch a sleeper? For all intents and purposes, the pure performance in play will be the same.
