I have also noticed a thin trailer makes the bait more likely to hunt. I want to be able to get the bait to hunt on a constant retrieve...which about 1 in 5 will do with a thin trailer. (I prefer the old Burke trailer, but the Zoom Spinnerbait Trailer is OK, too.) The original RAD Chatterbaits would consistently hunt. But, the Z-Man baits do so far less often. I've played around with the size of the blade, a little with the shape, and with the size and diamater of the eye that the blade attaches to. I use a Do-It Sparkie mold, so it has the regular eye style, rather than a flat eye. So, I haven't played around with the split ring to the blade design yet.
