I'm mostly an english rider, and when I competed western, it was on my mare that was too old (by that I mean 7 or 8 ) to compete in a snaffle or hackamore. I just remember my trainer saying something along these lines.
My trainer started her show gelding off in a halter, and now he has a very soft mouth... it may just be him (quite possibly) or the fact that he was started with a halter.. I'm not sure :P
