That’s interesting about the Flyover . . . I tried one once and really liked it, but needed the larger size and couldn’t find one used. Maybe I am lucky that I didn’t keep it!
I currently hunt in a County Extreme, which I really love. But then again, my horse has no withers so it’s fine. I also have a Schleese Peter Gray and a Passier Military. The last two do not have such forward flaps so they ride (at least for me) somewhat like an all purpose. The Schleese is very comfortable; the Passier has a hard seat but is very balanced.
I have an old Albion A/P that is a wonderful saddle. It’s the Original Comfort and it’s comfortable and secure. On the horses I have now, it doesn’t really work as a jumping saddle, but it doesn’t sound like that’s a real issue for you. I did have a horse that jumped with less of a bascule and I evented him through Training in that saddle. I tried the Albion Eventer (I think it’s the Krontrol) from Trumball Mountain and just loved it. Unfortunately, I need a M/W for my horse and the tree was a bit narrow. Even used it was at the top of my price range. One caveat on the Albions – I have my saddles checked regularly by a master saddle fitter. The flocking in the Albion seems to move around more than in some saddles so it tends to need to be “tweaked” more often than others. Still, my horses have always been very comfortable in them (no back problems!) and I find that they put me in just the right position.
As for pads, I use a Saddleright pad under my saddle. It doesn’t change the fit but I think it’s very good at absorbing shock. I have noticed over the years that my horses all seem more comfortable when I ride with them. The pads are $$ but they last forever. Sometimes you can find them used on ebay, too. I like them better than the thin line pads.
