Donald ... and others. YOu mentioned the weight factor when putting lots of pages into a 2" binder. Many years ago, I saw how one collector overcame that problem ... and created a very colorful addition to her pages as well. She would alternate the 2x2 pockets on each page with a matchbook cover in the adjacent pocket. This lightened her book significantly and made a very interesting, colorful book that even non-chip collectors enjoyed looking through.

That chip collectors name is Janice O'Neal.
