I found this on You Tube and I hope it is okay to share Dr Deb as it has a few things on saddle history that really make it clear on what we are looking at when we look at Saddles today and trying to choose the right one for our horses.
I haven't gotten the back issues yet but I have the Inner Horseman on Saddle fit. :-)
If the weather holds I am off to play with shims today as I have a few questions about them but need to go see if I can answer my own questions first.
A session with our Institute friend Dave Genadek is always going to be empowering for you.

Here are a couple of videos that explain the concept of cantilevering. This is a really important concept in the world of saddle fitting. I believe you should place rider forward and cantilever the rider's weight backward over the entire rib cage. Others believe the saddle should be placed further back and the pressure should be cantilevered forward. The third group believes the saddle should have even pressure throughout the length of the saddle. Depending on which of these concepts a person believes in, different ideas of how and where to place billets will emerge.
