1 weapon or 2 weapon

what better for dps 1 greensteel greatsword or 2 greensteel swords

[dkyle]

Best DPS, provided you have all the feats for it, is two Khopeshes.

For THF, either a greensteel Greataxe or greensteel Falchion is generally preferable to a greensteel Greatsword.

[Consumer]

Although you have not included your build two greensteel khopeshes will beat every other GS weapon/s. Halfling sneak attack enhancements favour TWF as they proc on each hand.

was thinking 12 fighter 6 ranger 2 rouge or 18 fighter 2 rouge
