I actually had my 128 quart igloo cooler seat (filled with my electronics, rain gear, downrigger weights, terminal tackle, hooks, extra reels) come undone on a drive to find it riding on my poles for 110 miles. I thought for sure Thy were all going to be broke. My one copper rod is roughed up on the back but only some scratches to the clear coat. I have ran the Cabela's rods, couple ugly sticks, wilderness, and diawa rods but my Okuma's see regular duty. I am a teacher and my summers are filled with trolling for eyes, trout, and salmon.
The medium 8'-6" downrigger rod is great for inline planers and big boards. I have caught hundreds of fish on these no issues.
One thing I will mention is I don't leave my rods and reels in the sun or weather day after day. After everyday they get put back into the barn until the next day.
