This goes deeper, however, than just figuring out if ravenous bass will eat new lures. I use these scenarios to note statistics. For example, say you're going to test artificial frogs among a school of crazed bass on a stretch of lily pads. The colors of the frogs you choose, and the action necessary to get bit often are surely important, but what you may want to look at are factors like strike to landing ratio, or how well the lure holds up after being trashed. In the particular case of frogs, I use a heavy bass feeding window to help me alter stock hook orientations towards better hook penetrating angles. It's a fine tweak, but necessary to have worked out for when I pick up that same frog during a tough bite. Otherwise, even something as simple as making a certain size hook lay perfectly on your plastic worm, allowing for both the optimal worm action and hook gap/worm relationship, is a very important process to work through. My point is, if you throw the same Texas-rigged lizard and it's rigged the same way every time you show up to the slugfest, you may be missing out on what an action packed day could teach you.
