I have used the Post-It product that is very similar. The drawback to them is that they are bulky and awkward to carry when your hands a full of presentation gear. I'll give the A-D product a try - it sounds like they're on to something with their roll idea. Thanks for the tip!

I've used the Avery single-sheet (27" x 32.5") for years; they're great. I frequently make headway on writing projects by holing up in a cheap hotel room somewhere with several suitcases full of notes and books, my laptop, and a pad of the Avery clink sheets so I can put outlines and notes up on the wall. Here's a shot of a recent stint, with just one sheet visible (there are others scattered around the other walls of the hotel room).

I do the same thing in my home office, although without the cling sheets.
