A campy question

[doctorbike]

I'm doing some serious mountains (on road bike) climbs this summer and want to modify my Campy record 10s from the current 29 to a 32. Yes, I need it, getting old. Have Compact 50x34 up front. From what I've read, I could put a 12x30 Centaur on it, without changing rear der. However, I think I have to put a long cage 2008ish 10s record rear d on to get to a 32. Can you folks confirm that. Plus, are there any 32 campy cassettes around? where do we find those.

Note; the old racer in me can't put on a triple. hehe.

Thoughts? and my legs (and bum knee) thank you in advance.
