I have never ridden in a CAIR saddle but from all reviews it's either a love it or hate it thing. Personally I went with flocked as it is easier to adjust and with a green horse if there was a bit of bounce I wasn't sure how that would go over. It is also cheaper but harder to find unless you buy new.
I bought mine used off ebay for half the price of the exact same used saddle at the tack store. It was very well taken care of and I'm sure it will last as long as I will be able to ride my current horse (hopefully at least 5-10 more years).
I will say the overgirth strap that is ment to hold the flaps down on the dressage saddle was a pain in my butt, it caught in my spurs all the time as I couldn't adjust it tight enough, so I cut it off.
I would look for a used saddle instead of buying new. Plus alot of people will throw in all the gullets they have as well when you buy used, which is a $90 value.
But don't be fooled about it being called easy change lol. It took me a half hour and lots of strong words. You basically pull the saddle in half and need four hands and two tools at once. So I told my girl to not change shape anymore.
