The Fisu Spool is the perfect accessory to add when you want to make a Fisu reel more versatile without having to buy multiple complete reels. A spare spool lets you switch from a floating line to a deeper-diving line, or set up a different configuration for reservoirs, rivers, or streamers. Changing the spool keeps the same frame, the same drag, and the same overall balance on the rod. The size must match the reel being used, as a #5-6 spool cannot replace a #7-8 spool. FlyScene also lists the #7-8 spool as compatible with the Vision VPK4909 pike fishing set.
