KP,
Been there. Done that. Hang my head in shame often. My shrouds have those plastic covers. We were out on a nice day and I decided to fix the rigging tape on one of the lower shrouds to get rid of a wild end that was just hanging. When I peeled it back, I found about 10 wires left. The breeze was light, and we were on our way back so we sailed on. All went well. Monday, I dropped it off with Worst Marine and said "Make mine a double. That was last year. This year I'll replace the upper shrouds for good measure.
