I haven't found a way to tell without fishing with the rod for a little while. I've had light rods that felt heavy, heavy rods that felt light, cheap rods that were sensitive, and big money rods that felt dead. You just can't tell without getting out on the pond and using it. Also be careful taking advice from "prostaff" guys. Their getting benefits from a company to promote a product, but that's a story for another time!
