All very good suggestions. Here's a couple of different tips.
While we usually like to keep it simple, we often add a couple of twists to eake out even more action when trolling. First, we don't bother messing with clipping our lines to DR's but we do use them to fly Fish Flashes below the surface (not too deep) to attract meandering schools when prospecting the outer rips. Secondly, when someone gets a hit on a trolled cut plug or spoon, the others will reel up and, while the fish is brought in close, will proceed to cast Buzz Bombs around the boat. What's amazing is that quite often this is when multiple hook ups occur. Seems like the first hooked fish attracts others to the boat and they just can't resist the falling Bombs.
