Justin: Maces
Sue: Bows
Feena: Whips and the +3 HP seed
Justin seriously needs to catch up in Vit (and will need the extra defenses if you plan on keeping him in most of the "Legendary" set for much longer), and Sue and Feena have way more than enough levels in their current weapons, so switch off. And Feena is going to want all the extra HP she can get eventually.
