Used this line in a clear mountain lake with shallow feeding trout. The camouflage core made a big difference—flies stayed hidden and I had several strikes. The sink rate is consistent and the line feels smooth in the hand.
Michael Gray –
Good for stillwater fishing in clear conditions. The clear coating helps avoid detection, and the 2-inch sink rate keeps the flies moving naturally. A bit heavier than expected, but that’s fine for the application.

Fished in a quiet reservoir with low visibility. The line’s stealth feature worked well, and the flies stayed in place without sinking too fast. Works perfectly with my long leaders and multiple fly setups.
