For $17??
You could drop the 11, 12 & 26 from the SRAM, use the 12T from the Forte and the 24-28 from the Nashbar..
IF you wanted tp get "crazy". you could pick up a 13-23 and you'd have enough cog selection to make bout any custom combination you'd ever need. Handy if you wanted to switch between Mountain & Road type use.
With the 2 cassettes I used in my original post, I can make a combination of 12 or 13 through 19 with 1T increments + 21, 23, 24, 26 & 28.
My riding is all flat, city type, although I still have the granny ring if I were to need it.
It's nice to be in "cruise mode" and be able to shift up/down 1T as the head wind changes. It allows me to keep my cadence in a very narrow range that works best for a decrepit old man!
I've been recently "experimenting" with different length cranks/rings, so I can rather quickly, change the cogs to "fine tune" my gearing.
