I built a few using the ultra minnow body and twisted wire shafts in the 3/8 size. I cant seem to get more than a couple casts and they wont track right. I have 2 combinations that I tried. one was #5 willow and #3olorado the other was a #4.5 willow and #2 Colorado. I have tried lots of bending to tune it but after a few casts have to re bend.
