Any question answered...

The 2011 Chorus has been nicely improved and ressembles 2010 record very closely (a few different materials 60g heavier). Because of the new logos 2010 stuff is popping up quite cheap. So price wise 2011 chorus is very close to 2010 record. Thing is, they made some subtle changes to the mechanics of all the ultrashifting groups for 2011. So 2011 Chorus might actually be better for all I know. Still working out how to pay for anyway, but thanks for the advice.

I've got one bike with Super Record and one with Chorus and don't really notice that much difference. The changes are a bit crisper on the former, but that's about it, bar the small weight difference.

If you do go for Chorus, I'm sure you won't be disappointed.
