All depends on what species, technique and how serious you are.
For drift fishing rivers where you need to feel the bottom, you will have to pry my G Loomis IMX baitcaster from my cold dead fingers.
You couple the ultra sensitive rod with power pro braided line and it feels like your finger is out there touching the bottom of the river.
The super light weight of this rod is unreal, combined with enough backbone, the right stuff will take you to the next level of success.
I use Loomis IMX str1084c rated for 8-12lb line and have no problem landing salmon to 40lbs, given the right water.
The same rod is light enough to play 6-10 lb steelhead without feeling like a meat stick.
I once grabbed a guy's Ugly Stick with mono line just for fun after years of using high end rods, and it felt like it was made of rubber.
Makes a HUGE difference, but like everything else in life the good stuff ain't cheap ($400).
