Wow... not sure I'd want to play in a league that counted errors.
Anyway, with those settings you are essentially triple-counting HR (HR, OPS, TB) and making the top sluggers with good K/BB ratios pure gold. You are going to be VERY happy with your infield, minus Jimmy Rollins.
The pitching categories looks a little more balanced.... you're double counting strikeouts (Ks and K/9) but you add walks, so Jonathan Sanchez types get a bump and a hit so it's a wash. You also count QS which bumps up starter value but add L to bring it back down. Roy Hallady is going to be a beast in this format. You need a top pitcher with few flaws... when you start talking about guys who have good K/9 and low BB, that basically equals top tier starter. Ricky Nolasco wouldn't be a bad starter in this format either.
I still say your pitching is weak for a 12 team league. Gio Gonzales is a nice find, but guys like Danks, Kuroda and Lackey are going to be pretty "meh." Double counting K's like that really makes this type of pitcher a bad deal. In this league I think I'd just roll with the BB punches and get Sanchez, Morrow, that kind of pitcher. It's H2H, so I'd focus on high K/9 and let the rest sort itself out.
