I have limited experience but have a Derby House Gp saddle which I love (tho it is a bit heavy) and an eventing saddle - Bates, which I aren't keen on, tho it is light, it is as boney as hell!lol.
Bridle wise, I've a Robinsons Requisite bridle which fell to pieces and I have cannibalised for spare parts..........
I have a nice plain black bridle bought from Derby House a long while ago, think its Tredstone (or Tred sommat?!)
And I had a mistake of a bridle (it was a cob size and was a crank noseband which I didn't like) which was very expensive and I sold to somebody on here. That came from a local tack shop but I can't remember the make!
