I assume you're striving to be a spin specialist (*hint* the answer is "yes"
). Strength is not that useful imho. Take it no farther than 2/1, but some will disagree. Vision is a bit overrated imho, so go no higher than the 68 cap. Personally, my guy only has 63 at lvl 72 and he's been a beast.
http://goallineblitz.com/game/player_awards.pl?player_id=961729For confidence, only train it when you're absolutely out of all other training options, and don't even bother 2/1 capping it. Some take it even farther, like Beachsand, but that was perhaps during the days of morale nerfs. Nowadays, Bort fixed some things, so it's back to not being a big deal anymore imho.
http://goallineblitz.com/game/forum_thread.pl?thread_id=3941266Jumping is good for "diving brTk's," but take it no farther than 2/1. Train stamina, but don't invest SP's in it (same applies to jumping).
To answer your question though: Go agility. You're very close to the 4/1 cap (67.97), so finish it off. Take it to 5/1 (73.25), or hell, even 6/1. Agility is paramount for triggering "Spin." Think BIG for both speed and agility. I'd say have both at 85 by lvl 72. ALG's should take you there if you 7/1 cap them both early. Carrying and vision, despite being major's, can wait as they don't need to be godly high, like speed and agility.
Btw, this is unrelated, but I'm not crazy about the +2 in Return Spec. Is that from AEQ or SP's? Regardless, I know it's tempting, but try to resist the temptation to dabble in SA's or AEQ so early. Two SP's can mean the difference between missing or making a cap early and AEQ in the 20's will be inferior later anyways, so you'll just be selling it and losing out on tokens.
