As an alternative, if you're sure you don't need the 11, consider a SRAM 12-28 cassette such as a PG-1050. 12,13,14,15,16,17,19,22,25,28. Personally, I don't like the mix-&-match approach since the shift ramps may no longer sync up with the neighboring cogs.

I also feel the same way about the first couple 2-tooth jumps in my cassette, currently a 9-speed 11-28. It's the main motivating factor in my desire to upgrade that bike to 10sp this spring.
