I guide up here in the mountains of British Columbia and typically spend about 3 months packing camps, gear and meat every day. my last season I kept a GPS in my saddle bag to log my miles and ended up with 1000 kilometers (600 miles) over the course of the season... I don't meant to say anybody else has a wrong method but in my experience the britchen should be snapped to the rear cinch ring not the front one, this prevents the rear from becoming loose or ending up bunched against the front one on long hard downhill trails.
I have also managed to cause sores (even with a good pad) by tying the latigo to the upper ring and a old time Idaho mule packer I guided a few years back taught me to tie the knot on the cinch ring, this reduced the bulk under the pack and I have never had a animal sore up high since.
now for my fabrication content of the post... do you have a suggestion for treating skirting leather to help protect it against sweat etc.. I have a horn bag I made and treated it with pure NF, the bottom of it sits against my horses neck and where the sweat gets to the leather it has turned completely black..
BTW; That is a really nice rig, I built my first one by trial and error without a pattern years ago and it works but I am sorry to say it is not nearly as nice to look at..
Cheers
