I have that exact model Aurora the 09' - got it off of eBay for less than $600. I like the stock saddle alright and I want to get a Brooks for it - eventually. However, my main concern is the Ritchey seat post with a slight set-back and no micro-adjust capability. Since "seat-angle" is supposed to be critical on a Brooks (I have a Brooks on my 520 - but it has a micro-adjust seatpost) I'm thinking I'd have to replace the seat post and the saddle --- just to ensure that I can get the Brooks fit just right.

Since the saddle will do for now. I'm keeping it until I have fewer expenses (house, bills, medical) and just dreaming of upgrades. As far as saddle height goes, I like to ride in a touring position - with the seat in a less aggressive posture than on standard road bikes.

I too never adjust a seat post more than a tiny bit at a time - and then readjust - 4 inches in one go - seems jarring.
