I have both rods, both are great rods too but there are differences.
The Fusion has a lighter tip and a more gradual transition to the backbone similar to a moderate action open water rod. When using a 1/16oz spoon, you can see a light bite on the tip before feeling it in the blank, almost like a Noodle style rod
The JT Shiver Stick has a faster tip, although I wouldnt call it x-fast. It also has a more powerful backbone and would handle a larger fish better than a Fusion
If Im fishing with the main target being perch or crappie with the odd chance of a small walleye mixed in, I use the Fusion.
If Im fishing for perch/crappie on a lake with more walleye or a chance at a 18″ plus walleye, then I use the Shiver Stick
