I don't really like the water blades. If you use the hose sheeting method as the final rinse, you won't have mush water to "blade" off. The one I tried left rubber marks on my roof (hard to remove).
I use the Absorber XL, and really like it. It's large, and has a waffle weave-type pattern. For ONR (winter) washes, I use MF drying towels.
Some people may claim product "A" may scratch your paint, or "B" one will, etc. If there is dirt or contamination on or under the item touching your paint, you will soon have swirls. This is the case with ANYTHING that touches your paint.
