my aunt rides in one and loves it. Absolutely adors it. It seems to fit on most of her horses, although she’s looking at the thicker pads for her current mount. that being said, she has difficulty during equitation lessons in it since it tends to push her leg forward, so she has invested in a wintec dressage for lessons.
I rode in one when I was trying out a horse and HATED it. Super wide twist, the fleece “grabbed” me too much, bulky (even though it’s light). I’ve been much happier with traditionally built saddles. I rode in a Duett Companion for a while, now in an arabian company solstice that I LOVE. I rode in a Mcclellen on my previous endurance mount, which was a good saddle, but not without it’s challenges.
