Bah Ulaks and claws arent really Old School EQ as they where out with Luclin

Anyway, the general consensus would be whatever weapon offers the maximum raw damage (and not DPS)
i dont know if the debate 2 handers vs dual wield has been closed, but it seems there are pros and cons for both.
Regarding favored weapon for group/solo, i'd say it depends on your monk style.
Myself as an harmonious monk, i like using a martial sword, the + parry with the def stance, gives good chances to parry attacks and launch counters that are really very effective, but of course this is when i tank or solo.
For DPS, i use 2 fistwraps i managed to get, but i suppose that with cash, i could get crafted gear way better than my stuff.
