That's what this is all about, trying different ideas and finding out the end results, the sounds , the sustain, the playability, through different people with on hand resources, just like yourself who had a spare tail piece and various cords and wires. If one person had to source all the items and try them all it could take another year or more to get the reults we are hoping for.The only difference is the cable is braded not solid. It is also covered with heat shrink tubing. I had a buzz on my ES9 Englehardt and replaces it with aircraft cable and fixed it right up. The wire that I replaced was solid formed wire. Braded wire is a known practice on acoustic basses so this should be fine on the Palatino. If not I have a couple of nylon tailpiece holders in stock here.
The web site bellow is what caught my eye, and it comes off the page on the Talkbass site when you click on the Double Bass page, if when you're on the below site and then click on his "Wood" button he has a variety of Tails, his testimonial button is also interesting.

I'm really looking forward to your results and comments with your tail piece and wire!
