I was having a big problem with plasti blade strikes breaking my cf tail boom. Wood blades are great but too expensive concidering they will chip so easily. I went to the lhs and bought a 4ft cf rod that is solid not hollow. It is a little smaller the the sotck (sorry don't know the size) but it is just a hair smaller. I wrapped two wraps of scotch tape around each end and it fit perfect and even took ca. It has worked great! No tail breaks with quite a few strikes. Oh yeah, I just ran the wires along the under side of the boom and taped them down too.
