@JackJ Which seasons and under what conditions have you had success with that bait?
Here in the Northeast, when the water is cold (50 degrees and under), the jerkbaits we use typically suspend. They don't sink or float upward when paused. Which, from the way I understand it, is the key to catching cold water bass in late fall, winter and very early spring.
The Shadow Rap definitely looks like it would work in more than just the cold water season.
