Is a western saddle supposed to be tight under the front bars when the horse turns his head or if his head is more up than a low headset? Naturally it would seem like it might a bit but just asking. Also I don't I put it too forward, maybe an inch or two behing the shoulder blade is where the concho is placed and in the beginning of the ride it seems fine as far as clearance in the front between the saddle tree and his body but when I ride for a while the saddle seems to move back (we did do a couple of steep hills). It is definetely not too wide. Should I be concerned? I did the wither tracings and pictures etc. and this is the saddle that was recommended for him, that was two years ago so I have done much research and am not totally clueless. My pad is either a 3/4 or a 7/8 5 Star, so it is a good one. Maybe a breast collar would be advisable or could it be too narrow, it is a wide fqhb tree? Thank you.
