I much prefer wool flocked saddles. CAIR is awfull. With flocking, you can alter the fit of the saddle and it will stay firm to the horses back. CAIR tends to bounce on the horse's back, and also compresses and expands to the rider's movement, putting uneven pressure over the back.
I have not known one person who stuck with a CAIR saddle, they all changed it over to flock within a couple of months. And these are all experienced, well known and reputable dressage riders, if anyone can feel a horse's movement change a dressage rider can, and every horse a CAIR saddle was used on here ended up with back problems that took quite some time to resolve. As soon as the saddles where converted to flocking, the horses were fine.
