Well then it definitely sounds like you need to go back to 'jumping 101' with this horse. IE: cross rails, lots of cross rails, get him in the middle, get him straight. You don't need hand gimmicks, you need even pressure in your legs, you need him to listen to you and go where he's directed. Grid work will help the rushing, little grids (ie: cross rails) with lots and lots of bounces, exercises to work on his 'woah' and backing him off from the jump.
IMO with those types of issues and jumping at this height are a recipe for disaster.
