Rigging tail up or down does make a difference. one gives UP pressure, and one gives DOWN. Rig according to how you want it to swim (or how fast you want it to fall, based on your retrieval speed). Also, if they were stiffer, they would not catch as many fish. Believe me when I tell ya, that the density, salt content, texture, and the stiffness of the bait, are all METICULOUSLY thought out, until the perfect balance is reached. It is an art and a science, and the guy that designs the baits is a genius at it, and will not release a bait until it's perfect. I also love the Cut'R, and use it all kinds of ways, including weightless, Rage Rigged, C-rigged, Tx rigged, drop shotted, swim jig trailer, and one of my favorites, the shakey head. My favorite color far and away, is Blue Craw. Glad you're having success with them, I'm sure you will have lot's more the more you use 'em. One of the best worms on the market.
