The absorber is just as dangerous, as far as scratching goes, as the CWB
The absorber itself will not cause any marring (nor will the CWB), but your surface is not 100% clean and particle free then the absorber will drag it along and marr the paint, this is obvious b/c there's no "knap" for the particles to get trapped in like when using a MF or WW.
When I QEW (most of the time): I use strictly WW's, usually only need 2, tops
When I traditional wash: I sheet first, then WW, and again usually don't need more than 2 rags to get it 100% dry.
If any spots show up after WW'ing I hit it with a quick QD and MF!
NOTE: I have both a CWB and absorber in my arsenal and still use them for specific jobs on occassion. The absorber and CWB are great for glass. And the absober also works well on wheels and door jams
