Have you tried Jumbo Mylar Tubing from Feather-Craft? Here is the Feather-Craft description.
"NOTICE: JUMBO MYLAR TUBING Large enough to slip over BIG saltwater poppers. MOST IMPORTANT: This is the size necessary for making the GULF COAST REDFISH SPOONS. Most popular with our redfish guides 3-miles from downtown NEW ORLEANS (call). JUMBO MYLAR TUBING in COLORS: (1)Pearl, (2)Gold, (3)Silvertone, (4)Greentone, (5)Coppertone. 18" PAK (Jumbo Gold is no longer available)"
It is too bad the Gold is no longer available. I don't know if it is big enough for a size 2/0 hook.
