I just switched over the ceramic last night. Did not notice a difference. I am having alot of issues with the wind. Seems each day has a bit of sun, rain and wind. Took August off, only did a few driveways. My old tip was clean, but left lines, new one did as well so I might have to adjust pressure again. Do I increase pressure to reduce lines? I can't remember what I did when I played with it last.
