Smith would be the lightest. PM Ksong for expertise advise, or check with Randy at Anglers Pro Shop...you might even end up with one of his Carpenters...hehehe
While the carpenters are great rods, I can not find any one who sells blanks. Right now carpenter complete rods are out of my budget. The Smith popping blanks are almost out of my budget, but no one meets budgets nowadays.
