Mine is an Isabell... kind of. Minus the price tag and somewhat lower quality, but it rides the same. My stirrups are REALLY long, couldn't ride that long in any other saddle but the Isabell demands it. You look like you actually have longer legs than your friend but because you ride short (as a jumping rider) you feel like her stirrup length is really long... am I right?
I couldn't ride in my friend's saddle for the longest time because she wouldn't let me adjust her stirrups and they were too long... she is 13, I am nearly 17, and I am a lot taller than her. Now, she can't ride in my saddle, because my stirrups are too long for her.
Nothing wrong with being used to riding short :) I'm used to riding long so I'm not really looking forwards to getting a jumping saddle that fits Monty because the suddenly short stirrups will be a huge shock!
