BTW, where did you get your single 16T 8 or 9-speed cog since either will do? .
I picked up a couple from Sheldon Brown several years ago. I took another single 16 from a low mileage XTR cassette. My favorite 9-speed cassette is a 13-26 that I made from Ultegra, D-A, and XTR parts, close ratios, very light and works great.
