I went internal and figured it out how to rig it right in there and I will never look back.
When done right it should provide you with many years of excellent and uninterrupted operation.
I was unluckly once where the line of the outside chaffed itself on a sharp egde on my gooseneck. One I missed whit my file when I build up the mast. It took me 90 minutes to get the mast of the boat, pop the diamond wires out of the spreaders, open up the mast. Stitch a helper line to the system, take the system out, replace the damaged line, close everything up again and step the mast. And I worked in a relaxed fasion.
I didn't feel it was a PITA. I have had no mishaps of any kind since.
