abl25,
I love DRY highlighters; couldn't do w/o'em For me they truly speed activation up. I will PhR, then ask some questions & open the book to the exact spot very often...dry highlight & move on.

I successfully did this for a somewhat complicated book on NLP. When i went back to the highlights, i activated it in no time flat.

Dry highlighters though, not the other. I use only dry highlighter pencils. First pass will be one color & the second pass another color. Color code it in the front for passes.

I have books that i never needed to MM b/c of this method. Unless someone has tried it, then don't knock my successful approach. It's fast like PhRing
