Indeed moonman the longer profile is typically very attractive to walleye but what is so appealing (at least to me) is the much wider profile than say a husky jerk or original rapala). It gives the lure a bigger "feel" and quite probably a bigger vibration while in the water.

After they discontinued the original husky lure (balsa, no rattle) I was lost for a while. I was not a fan of the loud plastic husky jerk lures and struggled to find a replacement that fit the bill. I had been eyeing the f-18 original rapalas (an excellent  night time trolling lure) and had already picked up a few. I also like the x-raps in the larger version but I actually prefer a quieter presentation. Alas, I was missing the original husky.

I can foresee these big flat raps and I having a long and lasting relationship :-*. Quite likely I will stock up lest I be without one but first I will give them a better test drive. They have 1 tiny rattle which I think might just be enough to wake them up without putting the big ones off.
