I am wondering if anyone has the new Tekna S line jumping saddle. I used to have the A4 (which didn't have the changeable gullet) and I loved it. But my mare needed a slightly wider saddle, so instead of spending the money to have it sent out to be widened, I sold it and bought my daughter her cute jumping saddle. I still need a jumping saddle though. So, I do know the S lines have the changeable gullet, but I'm more interested in the knee blocks. As a short rider I need to be able to adjust them, and the A4's were not adjustable. Anyone know if the knee blocks are adjustable? Thanks!
