Wow. That's a toughy. I prefer a medium heavy moderate fast casting for 1/2 oz and larger buzzbaits. Heavy fast flipping rod for frogs, medium moderate spinning rod for small poppers, and medium fast casting for larger poppers and walk baits. I even use my med light extra fast finnesse rod for casting teeny tiny buzzbaits.
So the answer to your question is ... "It depends"
If you are looking for a one rod does all I might try a medium fast rod, but you will find you might over muscle the hooks on smaller baits if you are not careful.
