Very good on the back of the Nasty Thumper also. Recommend the 3.8" and 4.3" Fat Impact.
Alex do you like Keitechs or a Zako more on your Thumpers?
Every lure is a situational tool to me. I like the Keitechs in the heavy stain/dirty water (8" visibility or less). They seem to balance the Thumper and it tracks a little more in-line than with other trailers. I think the extra water displacement and straighter-line helps the fish track my bait down in the dirtier water. I watched a few this Spring make a wake and come to it from a few feet away.
I really like the Zako for skipping. The bulk of the trailer helps keep the bait on top for longer. I'm not a great dock fisherman, but I can put that setup from one side of a large dock to the other. I found out pretty quickly that I needed to have at least two packs with me for a day of fishing with the Zako and skipping.
If I think the fish can see the bait from a couple of feet away, say light stained to fairly clear, I'll go with a LFT, Zoom Split Tail or something else that allows the Thumper to be a little more erratic. LFT Magic Shad isn't as bulky as the Zako, so the Thumper has a little bit more erratic action with it. A lot of guys from the North and Northeast U.S. have told me this is their preferred setup.
