I’ve used this line for several weeks on a local river and it holds up well under regular use. The sink rate is consistent and perfect for targeting deeper water nymphs. Easy to cast and doesn’t tangle easily.
Steven Newman –
Good value for the performance. The sink rate is exactly what I needed for bass in deeper sections of the lake. A bit more expensive than basic lines, but the reliability makes it worth it.

Fished it with streamers in a fast-moving stream and it stayed on course without breaking. The sinking rate is predictable and the line feels solid in the hand.
