Thanks...the balisters are 26'' aluminum by Deckorater's. (Lowes) Once you get the hang of it...they are quite quick to install. I think they look better than the standard 2x2 wood balisters, but they cost twice as much. They don't block the view quite as much either...and no maintenance.
I think I'll use 5/4 boards as rail cap. A 2x6 looked a little large up there.
