In classic, and pretty much until velious raid gear, knights didn't get the truly nice dmg/dly 1 handers. Massive dragonclaw shard, Ntov loot etc. So a 2 hander will ALWAYS do considerably more damage than a 1 hander + shield, and due to there being an issue with the ac cap on this server (or so i'm told) then AC from a shield isn't that much of a benefit.

So yeah, a 2 hander is probably the best option.
