I wouldn't do because....
- More Weight aloft
- Harder to wire
- Means of Attachment - How to make secure so as to not fall off and potential hurt someone below
- Environment - I don't think that the terminals are well sealed for direct exposures
- Sail/lines may get hung up on them and either rip them down or damage sail/spreader
- More volume to hear in cockpit and more volume means louder sound to neighbors
If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
