Which should I go for first?

Great blocker is pretty safe.
Showboat blocker is great if you get lots of pancakes.
Pass blocker is pretty popular as well.

Stonewall is probably a good one for guards.

I like Stonewall, a lot of NTs are built to reverse pancake quickly and then shifted over the RG, especially in 4-3 defenses. a 15% bonus to not being pushed backward or knocked down might not be a bad idea for a player that often faces the strongest player on the defense.

edit - Same thing goes for DTs and the LG.

Well, they suck pretty much ... but for my LG ...

Stonewall
Pass Blocker
Great Blocker
Football Genius (5 so far ...)

I've left vision at the second cap, so getting an extra 4.5 out of the VA when it's maxed out helps.
