If a person will use a little patience and feel instead of trying to use brute force and get instant results then they will have a much better result in the end and it will not take much longer.
Rather than trying to force the head down if you put light pressure on the reins and wait for the horse to find the right answer and then give a full release then you will be far more successful.
Although I agree with the sentiment of what you are saying, I do think that 'brute force' is a little over the top for a description.
I for the last 40 years have pooh poohed gadgets and gizmos, but you know they have their place, IF and I repeat IF
people know how to use them. With most of these things if used sympathetically and occasionally they can help a horse and rider progress, and no brute force needed.
This change of thought came after a year of battling with Mr G to get him to drop his head, he is another one with well developed under neck muscles because he has been a giraffe all of his life. At a training session last month we pooped a set of draw reins on him, it really helped me to see where and when I was dropping contact with him, and how to keep him in a better frame.
Would I ride in them the whole time, no certainly not, I never use them more than once a week, but we are starting to make progress.
I agree no brute force, but don't right of all artificial training aides in this category.
