When fishing in heavy cover, such as thick weeds, brush piles, or submerged structures, it's crucial to select a line that can withstand the challenges posed by these environments. Here are some options:

1. **Braided Line**: This is often the top choice for heavy cover fishing due to its high strength-to-diameter ratio. Braided line is less likely to break under pressure, making it ideal for pulling fish out of thick vegetation. A test strength of 50 to 65 lbs is recommended for most heavy cover situations. Brands like PowerPro or Sufix 832 are popular among anglers.

2. **Fluorocarbon Line**: While not as strong as braided line, fluorocarbon can be a good choice if you need a more stealthy approach. It is less visible underwater and has good abrasion resistance. A heavier test line (20 to 25 lbs) is advisable when targeting fish in heavy cover.

3. **Monofilament Line**: Although not as commonly used for heavy cover, monofilament can still be effective due to its stretch, which can help absorb the shock of a strong fish’s initial run. A test line of 20 lbs or more can work, especially in less dense cover.

**Tips**:
- Always tie strong knots, such as the Palomar or double uni knot, to ensure your line holds up under stress.
- Consider using a leader line if you're using braided line to help with visibility and stealth.
- Adjust your line choice based on the species you are targeting and the specific conditions of the water.

In summary, braided line is typically the best option for heavy cover fishing due to its strength and durability, but fluorocarbon and monofilament can also be useful depending on the situation.
