Will try to persuade Konishi-san to revive SP78EXH or UHL when I visit him later in the month , for some reason MH79XH isn't making a breakthrough in chugger only rod market in our region .
As for SP80M , I think it will handle Cubera 150 without problem but I agree , it is not an ideal rod for chugging heavier lures but then again , myself hardly use heavier chuggers nowaday , it's just too strenuous for an older person like me .
The size of a guy seldom being the determining factor on how long a guy can keep on chugging all day , a well conditioned guy will last a lot longer , in my opinion but yes youth is definitely help immensely .
Jon .
