People who hang on their horse's mouths, ride the brakes, pull back all the time, use a wicked bit with rough hands......you get the idea!
I am always one of the first ones to say the strength of the bit is in the hands of the rider, but then I am assuming everyone rides careful and has soft hands. Then I see photos (even in popular horse magazines) and people are riding the brakes and not giving their horse any slack- even western riders in curb bits. Ack! I ride western, I ride in curbs, but for heaven's sake give your horse a slack rein, the bit you are using could stop a train!
So yeah, that is my main pet peeve!
Another pet peeve is people who ride their horses a couple times a month and then get mad at their horse when it is energetic and full of pep. If the horse never gets out, what do they expect!???
PS. I know this is in the "English" section, but I think this subject surpasses disciplines. Has anyone seen the recent "Weaver Leather" ad with a barrel racer that just came out in some of the latest magazines? The ad is for their new saddle pads? Anyway, I know barrel racers feel they need some strong bits, but this gal seems to have a heck of a tight pull on this poor horse and the bit she is using is a twisted wire curb/gag bit. You see the curb action fully in function pulling back on the horse's mouth (with the twisted wire showing) and the rider has a heck of a grip on the reins. I KNOW the ad is for the saddle pads, but I cringed looking at the gal's grip on the reins.
I can't imagine how the corners of the horse's mouth survive without getting all tore up in a bit like that with that much pull going on.
