Just heads up. 3 guys on my syndicate bought Free spirit His ive rods and paid extra to have vortex air rod rings. After just a few months of use all the lads have numerous line grooves in the rod rings and have had to complain to free spirit who are replacing the rings at the companies cost. (With the FS guides)

If you do a search on rod builders, Harrison's cotswolds etc they are using these rod rings. Maybe it was a bad batch but having seen the wear damage inside the rings i wouldnt touch them.
