Echo SR 5108 vs TR 4113

Just wondering if anyone has any experience with the Echo SR 5108 or can compare that rod with the TR 4113 or the TR 4120? I currently have an Echo TR 4120 and debating whether to get a shorter stick which is comparable as most of the rivers I fish are smaller in size with lots of brush and overhanging trees. I have found a local selling his Echo SR 5108 for cheap and wonder if it is worth picking up. TIA.
