check out the GLoomis spinnerbait technique specific rods. I personally love the 812 model and it excels at 3/8oz spinnerbaits. If you want a heavier power you might want to step up to the 813.
Newly registered: Now that you've had time to try the rest,it's time to switch to the best.Pick up a Phenix Ultra MBX You'll not only have the blank you need,but the ergonomic reel seat design gives you casting accuracy for those all day casting trips. I use a Ultra MBX 700MH on 3/8-1/2 blades(ideal with braided line).If you like mono try the 700H both are awesome rods.Try it you'll like it!
