Weapons: I'd say you're on the right track with weapons, on HNM your melee will not get you very far at all, and in many cases you need to think about mob TP gain as well, so yeah... vilcan's staff + axe grip for the win. If you're going to use bow, definitely use Vali's, Ebow, or Selene's. As far as gun goes, remember that cannon shells only stack to 12, so if you're fighting anything that last more than a few minutes, Hellfire+1 with silver bullets will be more inventory friendly. The only reason you'll ever want an obow is for acid bolts, sleep bolts rarely work on HNM, and iirc there are sleep arrows anyways, just go get a loxley bow if it matters that much to you.
