and a deep-seated saddle on him literally squeezed me out of it in trot and blocked me totally in canter, I couldn' t follow the enormous movement of the horse.
When I first changed to the Ancient Passier, I felt like I was flopping all over. It took probably almost three months to become really COMPETENT in it. But my position is soooo much stronger now, and more correct.
There's nothing wrong with "help" for the casual rider. It is better to be 'helped' into a correct position than to continue strengthening the wrong muscles in the wrong position...
But Solero's quote is RIGHT ON.
There's also a point where you need to have a little more room to adjust position for different movements when training them.
I didnt know you could get a TC dressage any more. I am MADLY in lust with his jumping saddle. THANK GOD I have no use for it, because I certainly can't afford it. But I have never set my hands on a more beautiful piece of useful art. The leather and workmanship are To Die For, and the balance is impeccable.
One other design element which can very much affect feel is having half or Owen panels rather than full panels. Even on a deeper seat, the effect will be to sit the saddle better on the wide back, and achieve closer contact without 'hollows' behind the front/bottom 'edge' of the panels.
