I ride in an english rigged torsion treeless endurance saddle. One of the best changes I made to my set up is to get alum x-wide aussie oxbow stirrups, which I prefer over the EZ Ride stirrup. I haven't needed a seat saver, as my saddle is already comfy, especially combined with my equipedic pad.
FYI, another thing to consider for comfort is type of shoes you ride in. After trying out various brands of paddock boots, I became a fan of Mt. Horse. Then, last year I switched to the ariat enduro tennis shoe. My feet thought they died and went to heaven. The ariat tennis shoe is amazing and makes a huge difference in comfort when riding trails.
I live in the northern mountains of Utah with my wonderful husband, 5 horses, 4 dogs, 2 cats, 32 geese and 9 ducks. Life is good.
