New Saddle has Passed the Test

I bought a used 16 1/2" super wide Parelli Natural Performer via eBay. Last Sunday it passed the Cisco test. Today it passed the Lucky Star test. I tried to cinch it up tight enough so the saddle would stay on Lucky. When I mounted, it tipped a little,letting me know it might not be fully secure. But when I got balanced in the saddle and shifted my weight to each side, it felt secure. Off we went at a nice "trail walk" speed. I could feel those back legs…
