Don't know if this is the place to post this, but I've got a suggestion for future Bestiaries.
The bestiaries are understandably focused on evil-aligned creatures - most of the time, that's what parties are fighting. The issue crops up with Planar Binding - most of the time, PC's are binding good-aligned creatures (or failing that, at least non-evil ones.)
Could you try to tweak the Good-aligned outsiders so that they match up better with Planar Binding?
Lesser Planar Binding in Bestiary:
Evil Outsiders with 5-6 HD: Barghest, Bearded Devil, Nightmare
Neutral Outsides with 5-6 HD: Janni
Good Outsiders with 5-6 HD: Hound Archon
Planar Binding in Bestiary:
Evil Outsiders with 10-12 HD: Bebelith, Glabrezu, Hezrou, Barbed Devil, Bone Devil, Efreeti, Nessian Hell Hound, Rakshasa
Neutral Outsiders with 10-12 HD: Huge Elementals, Marid
Good Outsiders with 10-12 HD: Couatl
... see what I mean? It gets even more restrictive when you add Law/Chaos to it (Chaotic-Good spellcasters have a particularly miserable selection.)
I'm not asking for a percentage change of good vs evil in future Bestiaries, but could you shoot for the good creatures falling below the 6/12/18 HD for the binding spells? That way, good-aligned binders have as many choices to work with as the evil binders.
Anyway, let me know if this isn't the place to post this; new to the boards and relatively new to Pathfinder in general (3.5 convert.)
