i've been very happy with both my sensation dressage and my hrimnir (treed) saddles.
in either case i think the important thing is to get a good dealer and/or saddle fitter and a trial period is invaluable. (though i think long after my trial periods for both i'm going to want yet a *different* saddle, now that we've taken up jumping of all things....sigh! :) --vicka
