does anybody know why some people use curb straps with their loose ring or d ring snaffles? I see a LOT of western people do this and um, it seems to me that a curb serves absolutely no purpose on a loos ring or D ring snaffle.
I do this myself. A curb strap/lip strap as we call them in AUS, is actually very usefull on a snaffle. It prevents the snaffle from pulling through the mouth if you have to direct rein. It is used a lot by people who work cattle as you often have to really haul a direct rein to keep up with the cow, and the lip strap prevents the bit from pulling through the mouth by evening out the pressure.
