I read somewhere when using the Split Clamp to only use two of the attachment holes so the clamping mechanism isn't restricted.

When should I use the clamp and when should I use the hub?

THANKS!

For Tetrix axles, I was not aware that a Tetrix Split Clamp (W739078) existed, and searching does not pull one up for me. Where did you order it? any link?

I found a PIC of it in thr FTC Inspector manual PDF, in the section on legal/illegal parts. They probably both initially hold axle grip at similar level, but the set screw is more prone to progressive loosening than the clamp. The significant amount of hub protrusion that the clamping "fingers" cause, demands that swing clearance around the hub must accommodate this considerably longer radial reach of the fingers beyond just the hub's OD.
