What's good
- Gets deep at speed without the drag of a Dipsy — the fish fights you, not a disc
- Copper's thin diameter and weight give a very stable, consistent depth curve
- 300 feet is the versatile length; roughly 22 feet of depth per 100 feet at 2.5 mph
- Blood Run's copper is annealed consistently and does not work-harden as fast as cheap wire
What isn't
- Copper work-hardens and eventually breaks; plan on cutting back the terminal 20 feet each season
- Requires a large-capacity reel — a 300-foot copper plus backing will not fit a size 300 line counter
- A tangle in copper is usually terminal, not something you pick out
We list the drawbacks because a recommendation with no downside is a sales pitch. If a cheaper item does the job on your water, the write-up says so.
