Ghost makes an extremely nice pad, especially for the very reasonable price. Many people buy these for other saddles including BMSS, Freeform, and even treed saddles.
Bottom material options include sympanova (a soft rubber, easy to clean, breathable), black or white wool blend, and an amazing medicinal sheepskin. I recommend 1cm inserts with sheepskin unless rider is over 185, and for other bottom materials unless over 165 or horse's spine is well protected.
Add embroidery with your horse or barn name for extra fun!
I keep mostly black with sympanova or sheepskin in stock. Others may have to be ordered from Italy.
