My post was said tongue-in-cheek and dripping with sarcasm. I only meant that one way is not THE way. It's kind of berating to tell anyone (not just me)who has always used 'girth' that they were wrong and should be riding in english saddles. Maybe both of you are right and wrong. Everyone has to be so PC nowadays not to p**s someone off.
Anyway, original question was how tight should it be. It should touch the horse's belly but not be too tight and used as a 'bucking strap'. I think another purpose of the back girth (which is the word I use as I teach beginners and it is easier to remember and understand than flank cinch) is if a horse bucks the saddle doesn't stand up on the horse's neck (experienced this as a youngster and have ridden with one ever since).
qhr, If you had read my whole post including all the smilies and the part about a grain of salt I don't think I was trying to berate anyone. I was asking the kids what terminolgy was used around the different barns they ride at, as I was typing. A lot of us are rookies to the horse world and sometimes we mis-speak or are just flat wrong. Thats why I am a member of this forum to expand my knowledge and share my learnings and boast about my kids accomplishments. What I remember saying in an archived post was that at the barn Morgan takes english lessons and exercises ponies at the only thing you will hear is "make sure you tighten your girth or is that girth tight". Now over at the stable where Morgan and Matt do there western riding its "make sure you cinch up that saddle or did you pull that cinch tight". There will always be localisms and different terminolgy in any walk of life and for the best of me I can't figure out why you took that one statement out of context and thought someone was questioning the security of your knowledge.
No smilies for this one, cause they don't work.
