bottle dynamo mount

Does anyone have any recommendations on whether one should mount a bottle dynamo in front of the seat stay or behind the seat stay? I email manufacturer of my dynamo and they replied, "yes".

Conventional wisdom says that behind the seat stay will allow better contact whereas ahead of the seat stay will be safer if the dynamo becomes dislodged. But what you you guys think?

If you attach it securely, it won't become dislodged.

Even if it's in front of the seat stay and becomes dislodged, it'll still get tangled up in the wheel because the wire will still be attached. I'd say the primary decision factor is which way will allow you to get it better aligned with the tire. That seems to be the biggest issue with bottle generators. If they aren't well positioned, you lose a lot of efficiency (not to mention possible extra wear on the tire).
