I just got a HH Eldorado last week and am excited after riding in it a couple of times. It was comfortable to sit and our horse seemed to take to it just fine.
We got it primarily because of the various rigging options. Right now, we're working with the 7/8 position. The fact that it was lighter than some of the other saddles with this rigging was another major factor in our decision to with the Eldorado.
We had a tack shop help us make sure of its fit on our boy (QH, 16+ hands, and ~ 1200 #'s) and wound up going with this saddle's wide tree. According to the fitter, our horse would typically be in a medium tree, but each manufacturer's tree is different and wide seemed to fit him best in this saddle.
As I ride in it more and get him on the trails... It is very hot here and the buggies are definitely stopping me from going into the woods... I'll post additional feedback.
Here are a couple of pix.
When we were first looking at this saddle, I was really glad to read the posts on this thread!
