Generally, you won't go wrong with the normal spacing in the neck and F-spacing in the bridge. However, it doesn't matter which spacing you go with, really. You can rock a normal spacing in the bridge and it wouldn't sound that much different at all. Physics say that your low/high E strings will lose definition if it's vibrating a tiny bit outside the screw pole distance or whatever that it. Music says that your tone comes from your fingers. So yeah, if you're worried (like me), just go with the F-spacing. If you think you can't hear the tiny differences, you can go with the normal spacing. :rock:
