I rode for some time in an OF Feather which was a much older model, English style w/kneerolls. Very well made and held up beautifully to hard use. I liked it and it felt closer to the horse than did the OF Patriot or the OF Endurance. The horse went fine in it and I preferred it to any of the treed saddles, both custom and off the rack that I had tried before.
All of the OF’s that I rode however were made by the original maker and were not the ones made now so I don’t know how well made the new ones are. I’ve heard from several that they prefer the older models. I happen to think they are horrendously expensive now if purchased new.
That being said, my bad back and knees much prefer the treeless Freeform I ride in now. Lovely fit, excellent comfort for us both and I doubt I will go back. But if you are set on an OF, I’d get an older model off of ebay or one of the tack sale sites. They do hold their value well.
