I liked my St. Croix Premier spinning so much that 3 years ago I replaced a baitcasting rod with the equivalent. Love it too. Even if a different brand, something in the 7′ mhf or hf around $100-$130 should do well.
Somewhere over the 1.5oz range my Medium Heavy fast is starting to strain a little. Technically the rating is 3/8oz-1oz but it can be pushed a bit. Mepps Giant killers for example. You may want to look at a heavy fast, a bass flippin stick, or maybe a light musky rod for those big baits.
Where are you at in the pike belt? Seems you have some enviable problems.
