I have the orginal freeform and it's great. Much nicer than the bareback pad type treeless' (i.e the Torsions). Comforatble, stable and the horse loves it.
They have a resonable wither clearnce due to their shape but they wouldn't be suitable for very highwithered horses.
Bear in min she'll needs a really good pad underneath it - they are an intregal and essential part of a treeless. I use a Equitex.
