BALANCE did actually produce a Western Style saddle some years ago (both with and without a horn), but due to challenges with the manufacturers, Carol and Lesley decided to stop production.
It is very important to make the distinction that they were only ever (very deliberately) Western Style saddles, not Western Saddles; they were a BALANCE English saddle on the horse’s side, just with the ‘look’ of a Western saddle on the rider’s side. As such, they were never suitable for activities such as roping.  This is because in order for a saddle not to move on the horse’s back when you have another animal, in effect, pulling on it, it has to be so tight on the horse that it will disable full range of natural movement which BALANCE would never advocate.
It may be possible for someone to use a BALANCE Western Style saddle for some other Western activities, but in reality, the chances of enough riders having enough balance, self-awareness and commitment to helping their horse move in a natural and bio-mechanically correct way to make good use of them without encountering problems such as the saddle moving/slipping is very small.  For that reason, BALANCE has no plans to create a saddle suitable for Western activities.  There may come a day when BALANCE might be able to re-start production on their Western Style saddle in its previous form, but at the moment that is not looking likely.
