Well i personaly will also start to prefer Colorfabb, Simple because there quality is consistent,

Also the tolerance is so small you can always blindly press 2.85 in your slicer and just print it,
Huge choice of colors and there XT well i should try them again, I removed my fan duct a day or 2 ago, might be better now.
I should also try there woodfill again, as the previous times it didnt go that well to be all that honest.
Gonna play with my temp more as Woodfill goes. and lower mm/s.
