I think for a swimbait (a true swimbait - which I consider to be a bait that is consistent with the natural form of the forage species and produces a natural swimming motion without a lip) my goal is to replicate the natural motion of a fish, while being as close aesthetically correct as possible. I view swimbaiting as more of a finesse technique than anything else. If fish are on a reaction bite then there are plenty of options that are betters suited to cover water, and produce a reaction bite than a swimbait IMO. Having a bait capable of doing all sorts of crazy moves, or move at blazing speeds is really not that appealing to me as I have literally a boatload of other baits that are better suited to fill that need. However when I go through my books at the end of the year the trend that sticks out is that the majority of my big fish and pressured water fish fall for a bait that presents a nice consistent retrieve. Big fish (usually) are not reaction biters and are often used to seeing the "typical" presentations where I fish.....that is where swim baits come in to play for me; and creating something that will fill that void is what drives my designs.
