It looks correct to me.

I however have been incorrectly allowing the Str Mod for bonus to hit to be used with two handed weapon use.  Oops.

Should read these rules once in a while.

Hmmm.  So, a character with an 18 strength and 17 dex wielding Wc2/Wc1 would actually attack at -2/-2?  So he'd in effect have an additional -2 to hit?  If that's the case, high strength characters should never dual wield. 

My players who like to dual wield have learned to be tactical, because it's not so cut and dry. When going one on one with a challenging foe, it may not be wise to dual wield, as you suggest, JRR. But, when facing multiple lesser foes, the extra attack, despite the penalties, is often worth it, especially if your group embraces the optional critical hit rules.

 As a compromise you could probably house rule the secondary attack (only) would gain no bonus as you are focusing on the primary, thus stronger characters would gain some benefit.

In my campaign the dual wielders are typically the high dexterity non-fighters that use lighter weapons anyway and can minimize the penalty.  They usually have minimal or no positive strength mods so it doesn't come up.

Haven't had a fighter dual wield yet.  I think as they get multiple attacks they value the extra off hand attack less and don't want to use smaller weapons with penalties on each attack.
