I was wondering if anybody on this forum uses or have experience with rubber bits, especially snaffle and or mullen mouth. I live on a farm in SA and we have several farm ponies mixed breed mutts mostly that are used for "cow ponies" to gather cattle, look for lost goats, etc. My problem is untrained riders with extremely hard hands. `no matter how many times I tell them to relax their hands and not ride with such short reins, the less they listen. We have too few constant riders for me to try and train them, but in the meantime they're buggering up my poor horses' mounths. My equine dentist was here yesterday and recommended I put my horses in rubber bits/ bittless bridles. Now I was wondering whether to get some single jointed rubber snaffles or mullen mouth snaffles? I know the mullen is supposed to be the "softer" bit I'm scared that since they don't know the first thing about steering a horse with their seat it will only make them yank the horse around even more.
Any advice please?
