Faning - 0degree handle VS Angled handle

Been watching many videos on here of guys faning with an Angeled Squeegee handle for store fronts and even residential.

I learned to fan with a 0degree handle.

Opinions on both from the Vets on here?
Pros vs Cons?

Just saw that New Moerman handle…which is pretty much a mixture of both types of handles, because of the 2 pivoting points. So it got me thinking about fanning haha

Con of 0degree
-you can’t wagtail mod it, so you have to be switching it off the pole

Pro of Angled
-wagtail mod so you Don’t keep switching
