I think you are not ready to sell him. It's not all business. If you were ready to sell you wouldn't need to ask us. Keep him and enjoy him as you obviously do!
I voted Sell - my daughter is hanging on to 2 horses, neither of which are doing what she wants but she won't sell them on. If he is going to a good home where you can keep track of him, sell and give another horse your attention - you can't keep them all.
I said no as if its taking you this long with this much thought and you are this unsure, then you obviously dont wanna get rid of him. a horse of his quality and nature are hard to find,do you really want to give him away? you said yourself hes in ur top 2 horses.
Well I would originally have thought you would sell him, but am thrown by the smiley, so am thinking you have decided not to... How's that for making a decision? I'm as good as you! Okay... I'll go with sell.
I'm still feeling closer to the side of not selling. Today did not bring the outcome I was hoping for so I am now not sure about it all. No further forward I'm afraid.
