The hover line works great in calm lakes. My nymphs stay just below the surface and fish more naturally. The 0.5 inch per second sink rate is perfect for stillwater conditions. The textured markers help me keep the line in place during casting.

I’ve used this line for wet flies and it performs well. It doesn’t sink too fast, which helps with presentation. The 45-foot head length gives me room for long leaders and multiple flies.

This line is ideal for stillwater fishing. The slow sink rate keeps the flies high and natural. I noticed better hook-ups compared to faster sinking lines. The hang markers are useful for adjusting line tension.
