I have a BC Celeste, which is a “dressage-y” trail saddle more or less, so possibly not something an eventer would find useful.
That said, it’s a very nice saddle, well made, tough leather. I agree with others that they do not have narrow twists, if that is something you want.
One nice thing about BC if you buy new is that they have a lot of “semi-custom” options available at no extra charge – things like short flaps, gussets, etc. In fact my only real complaint is that there were options I didn’t know about that would have helped the saddle I bought fit my horse better. It is not a bad fit, but could have been better.
