The Patriot worked so beautifully with his Rocky Mountain 
Horse, and we have a friend who adores her Endurance Cutback so
much that I thought I'd give it a try....so...I struck up a
relationship with an Orthoflex rep.  I told her all about my horse
who was currently in a Saare saddle, but it just didn't fit right.
To make a long story short, she finally admitted that the type of
horse they have the most difficult time with are ones like mine:
Short Back - Well Sprung (he's 15 H and wears only a 72" blanket...
hence the nickname "Moose").  She suggested I try my husband's
Patriot, sans booties, to see how the panels fitted.  They didn't.
I appreciated her honesty.  SO...I'll be picking up my brand new
custom fitted DeSoto Custom saddle this week!  I hope it's as 
wonderful as everyone says....My friends love it.
But, you know, the bottom line is: it doesn't matter what success
or failures any of us have had with our saddles...YOU have to 
find the right interface for YOU and YOUR horse.  We're all looking
for a perfect fit in an off-the-rack-world.  And, anyone who says
one-size-fits-all well....they just haven't been shopping lately.
Good luck in your quest...and may the horse be with you.
