I am trying to rig up a Go-bar deck, but I don't want to shell out so much for go bars. I can get some fiberglass rod for pretty cheap, but I'm not sure which thickness would be best. From what I've read, 1/8" - 3/8" all seem to be used. What would be appropriate for a uke? Anyone know what thickness the Stewmac/LMII rods are?
