When I started I did not understand vortex technology and you know I still don't. I just think that the lip and the head about 1/4 of the lure is where all the action is, after that the lures hardly change. Color and a little flash make the lure. Now I am no engineer just a old guy that started from a 1/2" dowel and moved up to a 10" deep diving musky lure, but I did a lot of trial and error as I changed from one lip to another, now if I understood vortexes I could have save a lot of time. So thanks for all the information that you pass along it is needed and appreciated BIG TIME.
