well Don, that seems to be a loaded question, the trolling speed would totally depend on what i'm fishing. For example if I was fishing for larger rainbows chasing salmon fry, I want to run around 5 knots. But if I'm fishing waters like Stauffer, I think the best bet would be to back troll down stream, that way you can hit all the holding water. That said, I think trolling is for those who can't cast.
