Well, Netjak, I'd ask what your character really finds important.  For example, for a wandering monk I had, I used Desna, since he was constantly on the road.  For a clumsy orc who kept getting chased out of towns, I used Irori, for self-improvement.  Neither of them fit the character's alignment, but since I wasn't playing a cleric, I didn't think of that as really important: they were just deities the characters felt especially connected to and felt the need to talk to.
