Trading BAB for DR X / -, how much would you?

[carn]

Assume for a moment that after creating your level 1 char, your GM had a moment of confusion and offered the following deals:

permanent -1 BAB for permament DR 5/-
permanent -2 BAB for permament DR 8/- or
permanent -3 BAB for permament DR 10/-

As a melee, ranged, support, healer or sorcerer, which would you take?

I would probably go -3, -1, -2, -3, -3. (sorcerers do not need BAB, healers should stay alive, melee loves DR, only archer has not that great need, but DR 5/- probably still a deal)
