I’ve used the intermediate line for several weeks on a small lake. It’s easy to cast and the sink rate is just right for nymphing. The line feels solid and doesn’t tangle easily. Great value for the price.

The floating line works well from the bank for dry fly fishing. It’s forgiving and doesn’t snap when I’m still learning. The micro welded loops stay secure even in windy conditions.
Penelope Parsons –
Switched from a previous brand to Airflo’s sink 3 line. It performs consistently in deeper water. The sink rate is predictable and the line doesn’t kink during use.
