I use 2 1/2" flips but do not staple them. I use "cut" avery labels and only attach them on one side. That allows me to take the chips out. I put most of my chips in 1.5" wide binders. I find the larger binders are too heavy and the pages seem to sag. I use a zipped/padded binder for transporting my traders.

Here's a storage article I posted awhile back on chiptalk:
