My friend rides in Ansur saddles, as well as a bareback pad with stirrups - really comfy fleece one.
The ansur saddles were good in that they fit her hard to fit drafty type horses, but the ones she has tend to slip a bit. There is a whither pad to go under them for the horses with a bit of whither. When I ride in them, I find they can slip a bit, but the horses do go better in them than when she had treed saddles.
I have 2 that I ride in. My 1st is a "no name" and is super comfy for both horses & myself, never had any slippage. My newer one is a Bandos trail. I use a HAF pad with both saddles. I am having a little slippage with my Bandos so am working on tweaking inserts & girth. Both saddles are extremely comfortable for horses and I. I use them on a "stout" arabian, TWH, and my "shark-finned" ottb (I add a wither half pad for him). Check out the treeless yahoo group. They are very helpful and have a ton more information.

Does it stay put?
A lot will depend on your horses particular conformation and which pad and girth you use. On my horses any one of the models I've tried on them have stayed put beautifully through spooks, bucks, and hills.
