Lb -> 2h?

As long as your supply of onyx apples doesn't run out, 2h weapons will beat 1h+shield configurations.

Otherwise go 1h+shield. Your figures you provided are pretty close, and don't forget that speed of a weapon matters. In terms of DPS, your 2h figures would be roughly 70k damage compared to 1h's 68k (just making those up on the spot).

EDIT: Oh wait, I forgot that speeds with booster have a significant difference. Unless your 2h sword is a Fast(5) sword, you should stick with 1h+shield.

but then wouldnt that mess up the knockback with bigfoot? part of the reason he wants to go 2h is for the slower speed that works better with bigfoot.
