Boy is more forwards, but had tendency to lean am wondering if a Neue Schule Verbinded Bit would help? Generally I was always taught it isn't the bit it is the rider. Had to stop early as started to get abdominal pain again so have been madly doing my stretch exercises to try and ease it off but I felt quite lame once dismounted.
Have bought the boys
these in the Snuggy Hoods sale as thought would be excellent for winter as can stay on when changing from turnout to stable rugs.
