1. I'd use bow as switch on all of them except Haruspex who can get a spear in the second slot. With a point in Psionic Touch and investment in the Phantom Strike tree, bow Haru can become a bow/spear hybrid quite easily. Sage, Avenger and Ranger get nothing for spear, not even a LMB attack. So I'd keep them on bows. For bow switches, the primary bow is always about damage. So I'd avoid sockets like Anubis' Wrath and focus instead on Artemis' Bowstring or Valor of Achilles to max out damage. When you have taken damage and want to recover, you can switch to the secondary bow, which could be damage prefix (Relentless, Murderous, Veteran's, etc) with ...of Devouring as suffix and Anubis' Wrath socketed, preferably with +% attack speed as completion bonus. Suck back all that life instantly. But ADCtH is not the only viable characteristic of the second weapon. Don't forget resistances and special damage types either. Here are some examples: Apollo's Curved Bow: 84% Poison resistance. Cerberus, anyone? Astrapi: 90% Lightning resistance. Gives extra protection when kiting Typhon, Grays, Megalesios Atalanta's Bow: +100% Damage to Beasts. Cerberus, anyone? Also useful against those pierce resistant Turtles. Helios' Fury: 88% Fire resistance Painweaver: 64% Bleeding resistance. Useful against Yaoguai's gore attack. Sybaris: Great energy leech and ADCtH. Very useful if you're an archer who runs out of the blue stuff frequently. Instead of socketing Spectral Matter, just switch to Sybaris when you're running low on energy or health. Teucer's Warbow: 21% elemental resistance That's not to say that you'll necessary prefer these weapons to your primary. But it is something to consider. I would always sacrifice some DPS in order to get 80% capped resistance to whatever boss I'm fighting. Then there is the issue of those Undead skellies, their decent pierce resistance and their resistance to ADCtH/life leech. Your primary weapon may do a passable job against them. But I'd prefer a good damage secondary bow like Vet's of Annihilation socketed with something like Blade of Thanatos (+% Total Damage so it boosts both physical and piercing) with a completion bonus of +50% Damage to Undeads. In Undead-heavy areas, pair that bow with swap-out armour items like Bellerophon's Leggings (+60% Damage to Demons and Undeads) and Phantom Bane (+70% Damage to Demons and Undeads) and those Undeads cease to be a problem. You can, of course, also keep a bow in inventory with a socket that adds +50% Damage to Demons, and then use that as secondary in late Act IV where most foes are Demons. Unfortunately, it seems that ...of Necromancy and ...of Demonology don't roll on bows or, if they do, they're extremely rare. Nevertheless, the socket/Bellerophon's/Phantom Bane combo gives you all the damage help you need. In summary, your secondary weapon is not there to replicate the properties of the first, nor to give you an entirely different means of delivering damage (bow -> staff, for eg). It is there to address special situations where your primary bow may not be ideal. So there is nothing wrong or "wasted" about carrying two bows. Quite the contrary, it is a luxury and one that you should exploit to fullest advantage.
