I'm with Smrobs. What I ride is slightly different, but since I've discovered ranch saddles I've been a happy girl! The high cantle and seat pocket really gives you a comfy place to sit and spreads your weight "all over down there," not just on your seat bones. I can ride for 5 hours in these. It's the shape of the seat that makes them comfortable. Notice they have no padding.
I don't know if "Iridehorses" still has his saddle up for sale, but it is a 17" seat ranch saddle and it is SO well made. Much better than any of mine. It was in the tack for sale section of this forum. Unfortunately it was also out of budget at $1100. But man, that's a nice 17" saddle. Of course horse fit is that other variable in the equation.
But anyhow, since I've gone to hard seat, A-fork, high cantle, ranch type saddles I just can't hardly ride in a regular western saddle anymore. They all seem to force me into a position I don't want to be in. These saddles let you find your own body position.
Saddles should be comfortable. Not all western saddles are painful, honest! Some are downright awesome.
Aires, I'm so sorry to hear that saddle was a no-go for your boy. Ugh! I know the feeling! I must have gone through 10 saddles for my Mustang.
