Is it hard to get your leg back on a horse that wide, regardless of the saddle/stirrup placement?
Hmmm - to a certain degree you can... I think this photo (taken during a Dressage test) shows my leg fairly back (especially compared to the hunting seat above).

And this was taken at a cross country (yep... we got round a two foot course - great fun). It shows the suber pad under the wintec dressage saddle, plus my leg position with my stirrups up a couple of holes.

Please excuse the body protector - it's ancient and makes me look huge!! :blush:
