That was very severe JR!
Used correctly and infrequently they can be very benificial. I can ride perfectly well thanks and even i use them on occasion. Not very often mind!
I usually use them if my mare becomes rigid in her jaw, she may only be 15.3hh but shes stupidly strong and id rather encourage her head carriage with draw reins than battle with her and to keep nagging!! My pet hate is riders that nag their horses....it completely switches them off. I would rather use them once to get my point accross and then not needing to use them again or to keep asking and fighting!
She does not require them to be tight at all, and she is never forced or held in an outline by them they are simply an encouragement technique on my part, and stay on a max of ten minutes!
Anyway just my opinion of course! A horse should not be ridden in them frequently!!! This teaches the horse nothing except when it doesnt have them on it can poke its nose and do what ever it likes due to its head not being held down- thats when they are used incorrectly!
