Hi Karen,
First of all about the treeless saddle.
I did not like them for a long time... untill I came across the Barefoot saddles.
Sabine, a physiotherapist from Germany has designed these saddles especially for horses who have damaged backs or who symply never fit a normal (english) saddle.
For my horse Owen the whole saddle ordeal came to an end with the Barefoot London, for him finally a saddle that does not hurt his rather 'bull like' back and for me a saddle that offers me enough comfort for he classical seat and enough feel for the natural movement.
If there is someone in you neighbourhood who has such a saddle for you to try out for a week (that is how we work) then I suggest you try it.
Keep in my mind that you need the special physiopad underneeth and that you make sure you have the right pommel size for it to be a succes.
About the vaquera saddle.
Most vaquera saddles are to long for the horse for starters.
So I would suggest a vaquera mixta in a short version if available.
Keep in mind that it takes at least 2 years for the saddle to take shape and form and become comfortable for you as well as your horse.
You feel far away from your horse when your are accustemed to bareback or english dressage saddle even.
I know what you mean with the pommel in front... a saddle needs to be rather flat and level.
Especially thoses german 'deep seat' saddles are a menace to horse and rider. And mostly they do not fit, for al lot of people squeeze a size 28 chamber on a broad warmblood who at least needs chamber 32...
But people tend not to notice... they rather fight against gravity all the time it seems and damage their horse and their own lower back....
anyway, these are one of the important teachings the old master taught us, the level saddle, the seat etc.
But which I was burned down for mentioning, for some reason in the NHE forum. I still find that very strange. But hey, nevermind that now.
If you have anymore questions, please ask!
Warm regards,
Josepha
