I've read about the Sprenger bits and how they are the top of the line. Should I invest in one of them. Rode him today in a Myler low port and he's still playing games. Perhaps it's not even the bit, just me not being firm enough. I HATE pulling on his face but he was such a pain-in-the**** on the last trailride, fighting with a lead mare over first place that I ended up totally frustrated. My last horse loved to be last horse on a trail ride so this is real different for me. I want him to be happy so I'm looking for the least amount of bit that will do the job. Thanks!
