The SA Amplitude Smooth Trout lines are pretty much spot on to the AFTM grain weight specs, and my absolute favorite dry lines for trout.After burning through a few Rio dry lines, I decided to explore other options. Having had good experiences with their spey heads, I tied a Airflo dry line. It was horrible. Weird kinking that would never straight out, low floating, and a texture that was somehow annoying to handle.
Regardless, no more Rio dry lines. They just don't last. I wish someone could get the message to SA that their lines don't all need to be two weights heavier.
