These REC Fly Grips are exactly what is used on the better quality fly rods found in most retail shops. They feature quarter inch rings making a far denser feel and stronger structure. Lightly filled for smoothness and for sure not overly masked as less expensive cork requires.
Please tell us the reel seat you will use and the diameter of the recess if possible. You can also list the weight of the rod so we can ream close to fit.
