A weighty danny question

[steelhead]

Back in Nebe's thread on his herring dannies, there has been a very interesting and educational discussion on wobble vs roll in dannies (at least for me). From what I got out of it, with two belly hooks, the plug wobbles more and rolls less. One belly hook = more roll and you want wobble.... I was wondering, is the second hook adding a keel effect? Or is it the added weight of the hook and swivel at a critical spot on the plug? Do you think that with an equivalent belly weight of the belly hook and swivel located at the same location as the second belly hook that the plug would wobble more or still roll like before? Time to experiment I guess....
