Good to know, how well does white filament not clog up?
It really depends on the filament… The Super Bright White that PolyPrinter used to be able to get was one of my two top favorites - in the quality of my prints and in color.
Unfortunately, they can’t get that particular brand anymore. /sigh 
In my experience, most other white filaments seem to do OK. Though, I’ve used some that were not good at all. Yup yup ~ it varies quite a bit from brand to brand, and to some degree from batch to batch. Of course, all that can be said of most colors…
