The Rinfu SR (high-contrast) is still listed on the Diawa website at:
http://all.daiwa21.com/fishing/item/...puu/index.html
While the URL lists it under keiryu rods the Mountain Stream Rod webpage lists it under Fly Rod & Other Universal (Japanese: ハエ・万能竿・その他). A Rinfu 45SR only weighs in at 57 grams! No wonder they like it so well.
BTW - listed next under that section is the Hayakiri MC which in parenthesis they call Sagiri. Did they just change the name of the rod? People say it isn't available but people have been selling the Sagiri on eBay for the last year or so.
