I also make a sinking lure with Dave&Mark theory. The size of lure was 1.1cm(H) x 7cm (L), thickness is 0.5cm only, all side of lure is flat. Total ballast is 1gr
1. If i put all 1gr/1.3gr to the bottom-->no wobbling
2. 0.4 gr on bottom an rising 0.6gr up --> litte wobbling
3. 0.6 gr on bottom and 0.4gr up--> good woobling but just start wobbling after 2-3 secons (see in below video)
I think that :
a, the thickness of lure also effected to wooble action.
b, if the ballast weight too heavy or to light also make lure stop wobbling
Note: i hope that every one can understand my crazy English. lol
