Also, when I had a chance to handle one of the BnM Dockshooter rods, I found it to be a little too whippy for my taste. That was over 10 years ago, and I was using a 5' Zebco rod, which was a bit stiffer and more to my liking. Those that were basically my mentors to dock shooting were using 6' med action rods. A couple of years later I ended up with the ESP 5'6" UL to fieldtest, and I haven't used another rod as my primary dock shooter, since.
