We NEVER mind it when you think aloud Inverness!
It’s funny, because most of my life I have struggled against the exact opposite problem… Miss FeatherLight Hands here…
The good news is that my seat and leg is very effective for it, the bad news is I am forever readjusting my contact levels with my horse’s mouth when jumping or doing any collction work. Of course, a horse will give you a much prettier jump with some light contact (and hence engagement), especially as the fences go up, but I just seem to be a much happier soul cantering along in blissful floppy rein-ness
One thing an instructor recently told me was to think of both arms, the reins and a bit as a continuous electric circuit and contact should always be even on both hands - if it isn’t, you are breaking the flow of energy. For whatever reasons that has helped me with the correct “visual” to help maintain that continuous contact (but let’s not kid ourselves - galloping up on a loose rein to that deep spot at that 3’6 oxer in Asheville did a LOT more for my motivation )
