@kevtaylor makes the point about the rod being a good one, I would say, avoid Sonik and Avid Hybrid Spod/Marker rods.
On both of them I have had rings lose the liners. The liners fall out in transit, and on the Avid rod, the liner actually broke. I have had to replace 2 or 3 rings myself, and reglue the liner into the frame.
I'm not sure what rings they are but 'lightweight fittings' now means cheap to me.
