Trollin as in multi-pole jigs/minnows... or pullin crankbaits?

If it's the latter, I'd just rig up or get a couple fairly stiff rods, somethin
like you'd bass or catfish with, some 10 or so lb line, and pick up a few
300 Bandits. Maybe a couple each basic colors, white, black, pink, chartreuse
and let 'er rip. Trolling motor will work plenty good.
You can get a good idea of your speed by watching the rod tips wiggle.
Some days they want it faster or slower.
Just remember what you were doin when you catch fish and try to keep
it wigglin the same.
Just start pullin stretchs
here and there, and move around. Sooner or later you'll start happenin onto some
fishes, the more that happens, the more places that'll give you to try again
next time. I get all deep into it, but shoot - if you happen to be in the right
place at the right time, it's really awful easy. Gets lots of bonus fishes too,
bass, catfish, big bream even at times.
