You’re right, nobody said that. 
We all have methods that work for us, there is no harm in sharing them.
I think most are in agreement however that the main issue here is not needing a bit the horse “respects” more.[/QUOTE]
The way I see it, training a horse involves frequently opening the tool box for solutions that emerge. If a horse is heavy in the hand, it really is not helpful for us to just say, “Stop pulling, add more leg, etc.” One has to feel for what to do and when. Giving a horse a quick bump on one rein is one way to correct - but as I said above, and others have said, the bump has to be “just so,” very quick (but not a harsh jerk) and timed just right… One needs to experiment in order to get it right. For myself, I have spent 95% + of training, and learning to train, without eyes on the ground. So training is a conversation whilst the rider tries all sorts of things until something works. It is a puzzle, a challenge, and for many of us, the most fascinating part of riding a horse.
So we are all right. A sharper bit temporarily, can often help. Yes, this horse may very well need a different bit - longer term or for a few rides. I am a huge fan of the bit I cited in my first post. That bit, along with the Miklem, were a big part in improving scores close to 10% from one season to the next - for one of my horses. One of my current horses does exceptionally well to be put in a “sharp” bit every once in a while - but that bit is used with much leg (but not frequent leg). I am NOT a fan of “niggling” or constantly changing fingers/hands/ massaging/ or tapping with the leg. That just gives you a dull horse in the end. But even though the OP’s goal is a horse going softly with 2-6 lbs of pressure, that will not be where they need to go in the immediate future. IOW, throughness is not a short term goal. Submission is.
I will add that I have a bit in my toolbox that is highly effective with my young ISH now and then, the broken segunda. It is very severe if used in the manner that we use a regular snaffle. But it is NOT made for steady contact. If I put him in this bit, and then ride him very lightly but very forward, then I can turn him around in one ride. I have not used it for jumping. I hesitated to bring this bit up here as it is severe and could cause damage and I have heard of a solid Segunda resulting in lacerations in the hands of a pro who was angry with a horse and using it as punishment. Sitting in the mouth, the broken Segunda is not at all uncomfortable.
That being said, the bit is not the fix all. It sounds like the OP’s horse is still not balanced, especially at the canter, so would benefit from larger circles, shorter canter times, and lots of transitions. If this horse is as I think he is, I would probably be riding him for 20 minutes or so with up and down transitions, until he could be light in the bit. I would NOT use draw reins on this horse as I would be concerned that he would really really learn to lean. I would also not use a bit with any leverage, for the same reason. And unless using the Segunda, I would stick with loose ring, thinner the better, but then change it out to a fatter bit now, enroute to submission, connection, throughness, and all that sweet stuff!
OP, enjoy the process! Problems are puzzles, challenges, and lead to breakthroughs which can be truly orgasmic!!!
