Although we have used traditional stock saddles for years, I have found the cross breed saddle to be very comfortable as well.  A couple of years ago I finally let myself order a custom made saddle from Kent Saddlery. Turns out it was one of the better decisions I’ve made!  My saddle has a ‘stock horse’ tree and fits all but two of our horses, both of which are very high withered and difficult to fit with saddle anyway.  The saddle  also fit me perfectly from the get go.
