I've got a Savvy 704 and I agree it's too stiff for spinnerbaits. The 703 would work.
If you want to save a few bucks, I've actually had great luck with the Shimano Sellus. Cost about $50, and you don't really need premium rods for sensitivity when fishing spinnerbaits IMHO. I've got the 6'10" medium Sellus and it's great. That being said, I've never used it for anything 1/2 ounce or heavier because it's primarily my pond rod. Anything that heavy you can throw on your 704.
