Not sure that the depth of cup will add performance value against work input... But the sharpness of the lip is awesome... That will pay dividends for the angler and his physical effort in the "pop". Ideally, you would want to displace maximum water with minimum effort... But it will take one with more scientific background than me to make the analysis. Bottom line is... Have fun building lures, and have the incredibly deep sense of satisfaction catching fish with them.
