What I have always told people about riding is.
When you get done riding and your knees hart your stirrups are too short.
When you get done riding and your butt harts your stirrups are to long.
When you get done riding and they both hart your stirrups are just right :0 :)
Sorry I couldn't help it. Really I would know where to start other then to say the saddles you have ridden in do not fit you.
