Speed to 77, 80, or maybe 83, then switch to agility. I personally keep training the primary attribute until I've third capped it, after which I would unlock speed, agility, and vision and 30% enhance those. In the future when creating players do not boost to 4 until the last day of the off-season so you get more training in. That way you can actually cap to 49 at level 1 before boosting and get those ALGs put toward reaching the second cap.
