The types refer to the modulus of elasticity of the material the rod is made of. Typically a the higher number material eg Im8 vs Im6 will have the higher modulus. Having a higher modulus translates into using less material to make a rod so the rod will be lighter. Often the rod with the higher modulus will also be more fragile. Another factor as important as the modulus is the taper of the rod.

With all that said the most important factor of all in rod design is how the rod casts for you. That is what you should base a decision on.
