Thanks, luv! Actually the saddle fits my paint pretty good too, but I was just afraid to use it without extra-padding, because she doesn't have a flat back (ok, she's just built this way, not skinny ).
Around here, pretty much everyone uses this pads :)
On an english saddle, the pad is just there to keep the saddle from getting dirty. A few people actually rides without pad at all once in a while if no pads are clean at the moment.
Thick pads or extra things are just used if the saddle doesn't fit like it should.
I believe in western saddles you need a thicker pad since it's built differently.
And under most treeless saddles you definetly need special pads.
As long as it fits her back well it should be ok. Technically a saddle should fit well enough that you shouldn't need a pad at all. The only downside is that if she sweats a lot it's going to soak through the pad and stain the bottom side of your saddle.
Thats the kind of pad I want to get for my STB. He's got a great back, and his saddle fits perfectly for him, im lucky it worked out so well actually, the saddle was free, and its like it was costum made for him. I wanna get a thin pad. I have a contoured pad, and in the winter I put it on over another thicker pad, because I want him to have a touch of extra warmth, but the wider pad is just toooo thick. Pluls in the summer a thin pad will also be great for him
