I have a Bates Kimberley Swinging fender:
I love it, but I don't ride in it a lot because it isn't very practical for Mounted Games. But I show my Australian Stock Horse, so I use it for shows, and also for sporting and cattle work. I find it really gives me a good deep seat, and my horses slide stops of my seat are much sharper in this saddle. It sits in much the same spot as an english saddle. There are two different types, the one I have is a swinging Fender, and here is the same saddle in the traditional full skirt:
The Fenders give a bit more mobility of the leg, at least in my experience, and if you buy a good quality saddle you can decide where you want the fenders hung from depending on your style of riding.
A word of warning: Don't buy a cheapie stock saddle! There are some fo the most horrible indian leather stock saddles out there, they will be bad for you and bad for your horse. A quality stock saddle with do you for life and you will never regret it.
I'm planning on selling my bates in the future and forking out for a hand/custom made stock saddle by a fellow called Peter nelson down here, he makes really nice saddles with a very close contact seat and different design knee rolls, whcih will mean I canr ide mounted games in it. This is the sort of saddle I am hoping to get, only in a full skirt. You can see the more close contact seat and thinner and more pronounced knee rolls:
Please just ask if you want to know anything else!
