Look up "Get Bent" on ebay. Here in st louis mo, blanks 9' etc are about $33.00 + $8.95 shipping. Have buit 10 or more. They are 4 pce 7 wgt fly rod blanks. Never had a breakage. Do nothing but make crappie rods! Good luck. Just an added note, look at Airwave guides ($16.00); they are adifferent methof of casting and eliminate the line flap as the first guide is 19 inches rather than the 31 inch spacing most commercial builders use.
Good luck
