This is the NEW FS (Free Spool) Fly Reel. It is a shallow spool reel. We currently do not have double 0 fly line for this reel. If you are looking for a compact fly reel that will accommodate our double 0 Cortland Fly Line, choose our NEW DS (Deep Spool) Fly Reel that we have available. This reel is GREAT for ice fishing or using monofilament or multifilament lines. There are many applications that our innovative customers use this fly reel for. Just look on youtube.com for different videos created by our wonderful customers. :)
