Hmmmmm....what could "metal and the engine" possibly mean? An engine is made of metal - is that it? Nope. I'm talking about metal in the mouth (bit) affecting the engine of the horse (haunches).
I'd been riding Pony in a loose ring double-jointed snaffle, which she seemed to like enough, but it is a pony bit and I think maybe a bit too small for her mouth now (width-wise) so I thought I'd try something else. My friend was sending me some bits that she had for her smaller horses and until they arrived I tried a couple other bits.
First off, I thought I'd like to try something other than a loose-ring bit to see how Pony likes that, as she plays with a loose-ring a lot. I wanted to see if it was the loose ring's "play" that made her play with it or if it is the mouth piece or something about my hands.
I have an eggbutt Myler snaffle that I tried on her but it is too wide for her mouth. Tried it once and decided I didn't like it.
I have a couple D-ring bits, but they are definitely too big for her mouth as they were Tomato's bits (Colin's big TB that passed away a few years ago).
So I went off to the consignment store to see what they have. Found a simple plain snaffle with a small D ring. Now, mind you, I have never been a fan of the plain single-jointed snaffle because of the way I think they work, but I know some people swear by them so for $15 I thought I'd give it a shot.
Before I rode Pony in it I ground-drove her and double-lunged her in it just so she could get a feel of it. Interestingly, when I first put it on, sans reins, when she was chomping/moving it around in her mouth, she moved it to a position that it wouldn't be in when reins are attached - she rotated it down in her mouth, which I thought was interesting.
There were two takeaways from my experiment with this bit, and both reinforced my position that I don't like a single-jointed snaffle. The first is that for the two times I rode her in it, without even having real "contact" (just a light contact at the walk down the trail), her hind end sort of gave way....don't know how really to explain it except to say that one hind foot seemed like it got stuck in a hole or something. It didn't happen throughout the whole ride, just once or twice when starting our walk. She hasn't done that before and so I was wondering if she hurt herself somehow in turnout. Once we started our ride she didn't really do it again.
The second takeaway from this is that she was chomping the bit a LOT - just about constantly - with the single-jointed snaffle in. I haven't really noticed that before as a constant. She's done it here and there (last time I noticed it was at the little show and I think she had to pee because after the class where she was chomping, she did have a big pee and then didn't chomp anymore). Of course I wanted to make sure it wasn't my hands and that I was hanging on her or anything, so I spent most of the ride on a loopy rein walking and trotting around and doing transitions and figure 8s, checking in with myself and what my hands were doing.
Those two rides were on Friday and Saturday. Friday I actually was trying a new saddle (that I didn't like) so didn't even really ride, just wandered around a little bit.
The next day, Sunday, I put my friend's bit on my bridle. It is a Myler D-ring comfort snaffle. When I first got it I thought it would be too small, but I put it on and it fits just right. We went for a trail ride and had a nice long walk for over an hour (crossing both waters - yay! - well, jumping one and walking through the other). It was such a nice relaxing trail ride. No wonky steps, no chomping at the bit, just walking and taking in the sights and sounds and enjoying the day. Then yesterday I had a lesson and again no wonky steps or chomping at the bit. We are working on the quality of her canter and good departs and did some really good exercises. I'm focusing on dressage at the moment as I want to get her canter better before going back to jumping and cantering courses.
I've got another saddle coming on trial and fingers crossed that we both like it. I've tried two County Competitors now and know I like the seat and Pony fits in the wide tree well. I just had to figure out the combination of tree size for Pony and seat size for me. This one checks the box for both of those criteria.
So I stick to my guns about the types of bits I like. The metal in her mouth does affect her engine!
