Looking into buying a new CB rod, I know this is a dumb questions but iv always wondered about it, I have a few quantum 7'11 and halo 7'11 cranking rods and my dad has all Shimano, my rods are light but very big around and very limber on the other hand his 7'11(Shimano and st.croix) are small in diamnter and I like the feeling of his more than mine! I just don't like the feel of a fat rod that's that limber just wondering what is the differnce in the blanks the rods are made out of or the material! They are both for deep divers but why the size difference. I do not want another fat rod just want to know the differnce so I'll stay away! Thanks
