Just want to share my experience (first one) with the saddle fitter. Since my horses are not exactly easy to fit I ended up inviting a respectable local saddle fitter (recommended to me by lots of people).
Well... All I can say I did NOT waste my money. I learned a lot (and she was very good explaining why it does or does not fit). I was also amazed that she suggested very easy ways to help with the fit (like using no bow folded as a "step" to fill the gap on my qh's right shoulder).
We tried 6 dressage saddles and 3 jumping saddles and it was very interesting experience with each saddle. My horses are not easy-to-fit shaped (unfortunately), so most saddles sit really bad (and even with re-flocking and all they won't be the best fit). Also my qh is asymmetrical (surprise!) and paint is butt up/not flat back/and wider.
For those of you who have hard-to-fit horses... From my experience it's cheaper to invite the saddle fitter than buy a saddle, which is not a good fit, and then try to sell (usually loosing money on that) or fix by using those fancy pads (which don't fix truly bad fit anyway).
