I have a Fairfax and it has 3 long billets attached. They all get tucked in the girth (Mattes girth) so it’s no bother to me. I could have the “extra” one removed but the flexibility is nice and as I said, not bothersome.
I have a horse that wears a dressage girth one size larger than needed probably, but it works for him. I see some riders with teeny tiny dressage girths and a lot of billet showing. I don’t know how comfortable that is for the horse, but I think it could impact stability too?
If it works for the horse, it works for the horse. Some are fine with point billets, others aren’t. I think people overlook billet configuration because they are more concerned with the “top portion” of the saddle. Most billets can easily be changed by a qualified saddler.
