Today I took these four plugs down to the reeever. The plugs are made from cedar and are 6 inches long and just under 1/2 inches thick, big guys. Starting from the top and going down the lip slots are cut at 60, 50, 40 and 30 degrees respectively. Each of them has an upper and lower tow point drilled into them. I tested each with a large bill and small bill (shown at bottom of pic) and at both tow points, a total of 16 tests, 4 per bait. The 60, 40 and 30 all ran very straight in the water with the small bill, diving to about 5 feet but had almost no wiggle at all. These same baits all had good action with the large bill in place diving to 5' or more, the 60 version was more of a wobble than wiggle which is what I am looking for part of the time.
Now, here's my question. The second bait from the top, cut at 50 degrees is the only bait that would not run BUT it is also the only bait in which I had already inserted the weight. All the others I had the weight rubber-banded in place as you see on the top lure. The lure that won't run sits in the water at the same level and aspect as the others and has a very similar amount of weight.......so what's the deal? I am guessing that the center of gravity was changed too much with the large weights I installed. The weights are long enough to where they extend to at least the mid-line or further (toward the dorsal) in the bait. Any suggestions on how best to handle this?
