First off, snaffles (or any bit) can all be as equally severe, depending on how you use them. I would ask to try a few different out, since every horse is different and will work different off certain pressure. I do think you should spend time making sure you are communicating with your horse well in a lighter bit before switching to a stronger one. Because eventually you will end up having to switch again. I barrel race my mare in a Tom Thumb, don't ask why, she just loves it and is incredibly soft to it. I was asked to run her in a snaffle at a barrel race once, she hadn't been in a snaffle for at least 6 months. She stopped, turned and did just about everything she would normally do in a stronger bit. I like her that way because I don't HAVE to have her in a strong bit, but if I need a bit more bite for whatever reason, I've got it. Also, my mare absolutely HATES the Jr. Cowhorse. After I take her around a time or two, she works ok in it, but I would rather run barrels in a snaffle then that bit. I like Jr. Cowhorses, but my mare doesn't...try lots of options before buying. I hear the Loomis is a great great transition bit!!!! I really want to get one!!!
