C curves and J curves are not like black and white! No rod has a true C curve or tue J curve - all fall somewhere in between, just depends what your criteria is for pigeon holing them as either one!NAh!
i had CM in the past and they all have a C curve
still, ur not the 1st to say they have a J curve, but i dont see it
the tip tornado rods are what i would call a J curve
