Which is more important - lure shape or action or a bit of both?
As many on this forum know from my posts, I don't believe fish are fooled into attacking a lure based on what they think a lure is - two key words in bold. Fish react - period. What they react to has a lot to do with lure shape, action and presentation.
As I was making some lures in the basement, it occurred to me that most lures fish react to are linear in shape and whether a lure has eyes painted on (hard lures) or rear fins (Fin S Fish) is insignificant. Most important is how the lure moves and how fast it moves based on lure design limitations.
Most grubs produced have round bodies and many are segmented, giving them a bit of texture but also the appearance a bit similar to a worm of some kind. Mr. Twister and other similar grubs have been produced with that shape for decades, few anglers questioning the need.
But as of late summer of last year when I discovered a smooth bullet shape that caught everything that swims, the revelation led me to making short 2.5", smooth mini-worms, using softer plastic then that used to make most grubs - including the Fin S Fish by Lunker City. They have caught as many fish as the cone-tail grubs and proven to me that lure action matters most and that not all soft plastic designs are equal.
In the next few days, I'll put that theory to the test using a thin 2 1/4" worm rigged on a light jig head but with one difference: it will have four flat sides ending in the usual taper to the tail. The cross section is in the shape of a square - not round and the action will be no different than that of the rounded body version. Thicker grubs would most likely not work well with four flat sides seeing as how the roundness of the bullet shape body produces the waddle that is so effective at provoking fish to strike.
Lure action speaks louder than appearance much of the time and the proof will be in me catching at least a few dozen fish on a worm with four flat sides. I will report the results.
