I did 6 miles on Wednesday with it rigged the correct way. It seemed a bit better, but I felt I couldn't get it quite tight enough.
Yesterday, I had the whole family with so I couldn't ride, but I worked on mounting. (He avoids the mount by backing up). I had a successful mount and decided to try once more. I put my leg in the stir-up and started to get on, when the whole saddle slipped off to the side! Oops!
The cinch is made of a tough synthetic material, and it's tricky to pull it tight when it's through the 2nd D ring. I don't mind cinching without the back ring looped, but I also want it to fit right. Below is a picture. Remember that he is a curly horse with super long hair. It looks tight, but I promise that it's not (as evident by the whole thing slipping off!) :) Better luck next time I hope. :)
