Hi Krisse >>My legs are definitely further back when riding in the Sensation and in the pictures you can see that actually my heels are some of the time further back than any other part of me. Looks like I could (should) take the saddle a bit more forward so I'll try that to see if that makes any difference.
To me you mare looks like she is a little high behind? I think that your saddle should have some shims (beveled on the back edge) in the front as it looks like it is sitting slightly downhill in front, rather than put it more forward. The downhill will - cause your legs to go perhaps a little too far back and also press into her withers and give you the slight hollow and tightening in your back. This can also cause her to be more forward and hollow than you would like. What do you think Kaaren? Robyn
