It is good that you have a particular swim pattern in mind, this gives you something to aim for.
Go with your gut instincts, but be prepared to experiment with all the parameters of the lure, such as ballast location and size, lip size and shape, eye position, etc.
When experimenting, change only one thing at a time, or you will never learn what change worked. Make notes of the changes and the effect, this way, you will eventually be able to predict a particular result.
Good luck with your project and keep us informed.
