The last couple of years, I have had tungsten studs on the heels of the front shoes, and left the hind feet barefooted. Where my brother and I are hunting, the terrain is steep but not overly rocky. It has worked real well for us.
When the unit we were hunting was rockier and icier, the horses were sharp shoed on all for feet. Snow pads are as helpful as the sharp shoes.
We carry saddle panniers on each horse, rolled as tightly as possible. For the last few years, I have used thin dog collars to attach the panniers to the saddle. That works really well, the panniers can get snugged up tight to the cantle and it does not come loose, at all.
None of the horses I have owned have balked at packing meat. A couple were a little concerned, but all of them have packed without incident.
I had a carrying case made to hold a tripod and hang it on the off side front. Then the spotting scope hangs in a soft case on the near side front. Most of the time thou, they are left back at camp.
