You know, I WAS wondering if Ed might be experimenting with a dimpled material in his ducting. Along the lines of golf ball design.

I've been thinking about the ideal surface finish for inside our ducts. Who knows, maybe microminiature "donut bumps" will be all the rage by this time next year. I'm inclined to think that a smooth finish, however, is probably not the best.

Not trying to redirect the thread though! Show us more pics, Ed!
