Sage / Redington Warr
I had a DFR 1308 DBL hand. One day out of the blue [2-3 yrs] the tip section folded over with a sickening soggy sound.. Must have been damaged earlier. Anyway the Sage folks were great handling it. I shipped the complete rod [retaining my tube] and 20.00 for return shipping, about 10 days later a new DFR 1308 arrived. They may still have some replacments.
I think I've still got the email address for the gal that handled things if you'd like it.
Good luck... SG
