OH has offered very kindly to get me a saddle for my birthday. No budget but I don't want to take the p and so I reckon about £300? Second hand is fine. But what type of saddle? I have a GP one at the moment so I was thinking dressage. But my main plan for Cally is eventing. So what is an event saddle? Or a jumping saddle? How do they differ from a GP? I can do everything in my GP, really so which saddle would give me more diversity?
