I’ve been using Semperfli 0.2mm wire for my nymph patterns and it’s made a big difference in how fine and precise my flies look. The wire doesn’t tarnish and stays strong even after repeated use.

The 0.1mm wire is perfect for tiny dry flies. It’s thin enough to be invisible when tied, and the consistency of the winding makes it easy to work with.

I switched from another brand and noticed the wire holds better during tying. The 0.3mm size works well for larger nymphs and is more reliable than previous options.
