Hi everyone. new to the forum. and riding. not so much horses. lol. anyway, need some questions answered about bits. i just got a rescue horse a few weeks back who i also took lessons on for a while about two months prior. he's a great horse, listens perfect and does anything you ask. (can't understand how someone could have neglected him the way they did.) the bit my trainer suggested and used was a tom thumb. but the only bit i had at home was one someone gave to me and im not even sure what its called. its just one solid piece, with the curve in the middle. anyway, tacked him up and he did just fine with it. took it better actually. is there any difference other than performance in a bit? like, is the one i have okay for just trail riding? comfort wise for him is what i'm getting at. i'll only be riding him light and i don't want to use an uncomfortable bit on him since i probably wouldn't need one anyway because of how gentle and well mannered he is. if anyone could just fill me in and help me out a little i'd appreciate it. =) thanks
