So I've ridden Western my entire life. However, a friend of mine (who is an excellent trainer) gave me a brief lesson in English riding and I loved it. I don't want to do eventing or anything like that, I just needed help with balancing and my core muscles, and she said that riding English helps with that because you typically don't have anything helping to hold you up, like you do with Western saddles.
I'd just be using it for training at home and probably trail riding (I'd let my husband use the western saddle I have). I want to go to the local tack store, but I want to come prepared. Are there any specific questions I should ask? What are the "important" parts of a saddle, and what should I be looking for? I don't know anything about them, and I don't want to go into the store looking like a fool-- and maybe be taken advantage of. How can I get a proper fit, and how can I tell a decent quality saddle from a really cheap one?
