Well, I'll start by saying that I'm a newbie when it comes to experience with this rig but I have slowly started to catch some fish with it. I have only used the 5 wire Yumbrella rig with 1/8oz heads on Keitech swing impact fat swimbaits. A lot of people swear by the Zoom Swimmin Super Fluke Jr. in white ice color but I haven't thrown that yet. Seems like a lot of people prefer the rig with blades, I have a Yum Flash Mob Jr. but I haven't thrown it yet. It definitely seems to be a rig that produces feast or famine type results. If you do keep it in your hand and wind it as slow as you possibly can there is a pretty good chance that you will get bit at some point throughout the day. Not much help, just my two cents.
