I somewhat of a newbie myself at trolling but I was down at loz last weekend and caught a lot of good crappie. I use 10 lbs. vicious hi viz as well and use ugly stick catfish rods with spinning reels. I was catching crappie with about 40-50 feet of line out. Minus a couple blue cats all we caught were crappie. I was at the 45 mm we'd start in the channel and if we didn't get bit moved in to a cove.
