Actually, I have been curious about this too. It just says, "Wizards who select a bonded object begin play with one at no cost. Objects that are the subject of an arcane bond must fall into one of the following categories: amulet, ring, staff, wand, or weapon. These objects are always masterwork quality. Weapons acquired at 1st level are not made of any special material." The way I interpret that is you begin with a mundane item of Masterwork quality for free. Does this include things like composite bows at any strength rating? Also, it says no special material but does not say anything about magical quality or additional effects. Later it mentions adding on effects at an additional cost, but it says nothing about the initial creation. I want to play a wizard, but I find familiars are better for role play because of their vulnerability. So, I want to choose a longbow as my bond, but the rules for it are vague.
