Can anyone tell me what the main differences are between the current Max and Endurance series .. specifically the 734c and the 735c?

I have a Powell Endurance 765c which is a great rod. Super light and great crisp action.

I have heard the Max blanks are a bit stiffer than the Endurance.

Anyway...I will be picking up the 734 and the 735 in either series....just looking for some feedback before I do.
