Because it’s a saddle that I am unfamiliar with, I did a Google search and saw that mentioned in forums.

One user (chestnut cob) mentions it here http://www.horseandhound.co.uk/forums/showthread.php?565031-Harry-Dabbs-saddles
Went to their website http://www.harrydabbs.co.uk/dressage-saddles.htm and to my eyes, most of the saddles have very curved panels. So it wasn’t a slight, just an observation that it might be the wrong shape for your horse and that it was an aspect worth considering.
