I’ve had 2 JBN’s and have regretted selling them each time. The wide fit everything and I felt great riding in it. Never had a problem with sore backs or rolling (and my old horse has KS, so he’s extra sensitive to saddle fit!)  Now they’re scarce to find in the width/seat size I need now that I’m looking for a western saddle. I’m wondering how they compare to the Circle Y Tammy Fischer’s in terms of fit/feel for the rider and horse. I’m reluctant to get a tree’d saddle because I like the closeness of treeless, and because of riding multiple horses with growing/changing backs. 

I have ridden in both.  I love the JBN, way more real treed saddle feel for me, legs moved great and was able to really get up and ride.

I hated the Tammy.  The way the pommel is so straight up and down really made it uncomfortable to really get up and ride.  I'm a little chubby, it poked me in the gut when I went to get forward.  

I've ridden in both. I have a JBN for one horse because it works for him, although I typically prefer Caldwell's. I absolutely hated the way the fenders felt on a Tammy I rode in one time that belonged to a friend. They tied in too low and I couldn't get my legs away from it. I'm short but I felt trapped.
