List of trainers, clinics, etc, presumably they have a forum too. Helpful group.
There are some very helpful members on here who ride western too, I am sure they will be willing to give you some pointers.
How experienced with all things western are you?
Is your horse western trained already, or are you planning on riding English just with a western saddle?
There are loads of instructional videos about putting on saddles correctly, exercises etc.
I have no experience of western riding whatsoever.... the saddle I have ordered is one from Snowhill and is a cheapy. If it doesn't work out, I'll sell it on e bay. I can manage stuff like neck reining and think I ride like a cowboy slightly anyway....
I am afraid that the asian tack is mainly awful, generally very hard leather for a start, you can soak it in a vat of neatsfoot for a month and it still comes out rigid Been there, done that .
I think your best bet is to actually ask on here where people would recommend getting a decent western saddle, there are several reputable western stores in the UK and they probably have consignment items that are no doubt a lot cheaper than a brand new saddle at 4 figures.
Western saddles are notoriously difficult to fit properly, and have to be padded correctly, espeically due to their weight.
Although I LOVE riding in a Western saddle, I'm having to content myself with the occasional holiday to the US
The first time I went to a saddle shop in Montana I was astounded at the range of saddles there are, before you get the to the skirting and fender arrangements!
