Ample Prosecco
Still wittering on
I always try it first without the back strap. If you feel you need the strap, start with it loose and tighten gradually until you have better brakes. If you put the reins on the large ring it becomes a snaffle so no advantage.
I was not sure about the back strap, but when it was on her and I played around with it in the stable, it looked like the bit would just rotate without the strap? I wondered if that would actually be annoying!
