I'm going to stick my neck out here and say it's hard to get a handle on just what is going on with you and your horse. You ask for advice then say you "already know that" or are "already doing that". Why, then, do you need the advice in the first place?
When people reply on here and it's not what you want to hear it usually means you should listen. Did I want to hear I should not ride my horse with a cracked hoof? No. Was it true though? Yes. Please, please, please, be honest with yourself about the condition of your horse. It's to easy to ruin a horse. My OTTB has more heart than brains and would run himself to death if I let him. Your horse will want to please you weather it's in his best interest or not.
All that being said. You will do what you want to do. Just be careful and remember to listen to those whom you ask advice from.
