I'm planning on picking some up from CT Rodgers when I see him in Reno. The Wendleton's have a great way of using them for their hundreds of traders, they have trade/sale examples in 80 pocket books and when you indicate to Dave or Carol what you need they match the sticker number on the chip pocket to their numbered 20-40 chip tubes containing duplicates.

Of course, red chips remain problematic since a few fade and/or transfer color so take that into consideration when stacking them in tubes. The same thing happens in flips and pockets but usually the problem lies in the chips themselves. Most red chips however seem color stable and usually present no problems. Your milage and luck may vary.
