Getting a new bike!

[Grits]

My LBS is having a Black Friday sale, (no sales tax, plus deep discounts on many items). I went today and tested out several Madones. I have it narrowed down to either a 2010 5.2 WSD or a 2011 5.2 WSD.

They both feel equally comfortable. The main differences are:
2010 has SRAM Rival, 2011 has ultegra
2010 has bontrager race x lite wheels, 2011 has bontrager race wheels

The 2010 bike is $200 more than the 2011 - due to the upgraded wheels. It has been pretty heavily discounted. I priced the wheels separately, and the race x lites would cost $500 more if bought separately.

I have always ridden Shimano, and was surprised at how much I like the SRAM. It felt very intuitive to me. Really, I guess the only thing holding me back from the 2010 is I don't like the color as much, but I don't dislike it, either.

If anyone has any input, it would be welcome! I know I'll like either choice.
(I am not interested in looking at other brands of bike.)
