Ive always used an 808 for fishing. Ive considered a retriever but have a question. Does the line, ever get knotted up in the bottle? If I get one, should I be concerned with posible line tangle? I assume its not an issue, because so many people are using them. I know when line sets in a pile, it always finds a way to tangle up, so it leads me to being a little leary.
