Prop Hub Width

[Arbello]

I tried to find previous posts, but I was unable. Forgive me if this has been mentioned before.

At which point to Octura prop hub widths go from small to large?

Right now the dog I'm running is wider than the prop hub I am running, so there is a ledge. Does anyone know a general rule of thumb regarding prop hub widths?

Secondly... how much am I going to notice my prop hub being more narrow than my strut and dog?

Thanks!
