i have fished with guys that have beat me in tournaments with them and i have had partners catch fish with them after i stopped getting bites on rattletraps for the mourning and they do work (best in the early spring) but he did loose a couple of fish and i've heard if you fish it like a jig you will hang up and loose them a lot. if fished like a spinnerbait they seem to work well withboth the skirt and a fluke trailer is how they look the best to me, don't know how the fish feel?
i bought a kit and built 100 but i haven't made more than 3 cast with them, i do love the vibration and looks, just don't use them enough, but next spring i will.
i have a buddy that told me just 2 weeks ago he had a 8.5 and one over 5 on one, this was his largest bass to date, i was surprised that he was getting fish on them this time of the year? so they have to work.
