Dudley, curious, what difference does the number of sections of the rod make?
You are still going to have to send the rod in for repair if you break a section of a 7 piece rod or if you broke a section of a two piece rod.
In all of my years of experience I have seen more tips broken then any other sections regardless if the rod is 2 pieces or multi pieces.
The second most broken spot is the butt section.
I have seen other sections broken on multi piece rods but rarely.
