There are good and bad opinions about them on internet. You are talking about Circuit, right? I personally never tried the dressage one, but I did close contact and I found it to be very comfortable. I ended up getting more cheap Collegiate though.
Yeah the main complaint I have read is that the stirrup bars are a bit too far forwards so you have a tendency to have a chair seat in the saddle. I found one for $300 in good shape, but I am thinking that the back panels are going to be too curved for my horse.
