No offense but you need to have your eyes checked.I can walked into a room and spot right away stipple and the difference between the two on smooth walls.Dont kid yourself Kdpaint.:whistling2:I was originally taught that 1/2" and 3/4" covers were for textured surfaces, because they leave too much stipple on flat surfaces. That is total BS. Larger naps hold more paint, and due to the same weave pattern as smaller diameter naps, they leave the same finish when used by a pro. More paint, less dipping, more production.
I work in New England. Textured walls barely exist here, smooth is the norm. I have not bought a 3/8" nap in 5 years. I think they are production killers. Maybe, just maybe, on a level 5 I would use something like a 3/8, or smaller :blink:, but I bet I could use any high quality 1/2" nap and make it perfect.
Arroworthy make nice covers, as do Wooster.
