Yah speed should definitely go up a bit. I'd get it to 50 then continue to alternate between that agility and the SA tree for a little. Your vision is covered for a good amount of time.
Wow, your lvl 14 FS has more vision than my lvl 21 FS
Basically, what the guys above said. Speed should be priority, get it to 50, then go agility and a few SAs (Super Vision!!! put some in there ) and strength and tackling could do with a boost as well, but it all depends on if you're missing tackles or not.
