Feel will be her BIGGEST MOST HUGE learning tool !! Quincy is so right on that one.
As a example. I was put on a 4th level trained mare a few weeks back for a half a lesson to get the feeling of her back end "working" I simply could not figure it out riding my own horse or was at least not understanding what I was meant to be doing. Well shit let me tell you that was the light bulb moment of all light bulb moments !! Because my trainer basically took the forward thinking step of putting me on the other horse I was able to actually learn what she was teaching me to feel

The trainer from what you have written I am assuming has horses shows etc yes ?? Is it at all possible he can place abby on a well trained show horse to give her the feeling of what she is meant to be asking for and getting from her own horse eventually ?>
