hello,
so first, I have a fiberglass boat. If I run a rubber snubber from my downrigger cable to my ball will that stop voltage issues, from the cable.

second, I am fairly certain I want to stick to cable as I am old and set in my ways, and I have old downriggers that are not in beautiful shape, I took one in for service the other day and the kid called it an antique. so I am sure I would need to replace pulleys and stuff with braid. I do plan on checking the voltage next trip out to see if the boat is still running hot, I had issues in the past.
