Well it looks like you have a decent build plan started for him, were you supposed to have Custom EQ by now and didnt maybe?
Keep capping agility till at least 69. Get quad training going for vision/speed/stamina and use the 4th train on tackle. I would get tackle and vision above 48 once they are trained to at least 31, then continue on and raise tackle to at about 69. Then do the same for vision. After that its up to you, whether you dip into SA's or cap another stat first.
