After testing several dozen carbon shafts from arrow, kite and pole suppliers, I settled on the Victory V6 V-Force 300s as the best for strength to weight. Weight is about 9.75 grains per running inch (~.265 oz per foot), compared to 8-9 grains for most others, except the Easton FX, which are heavier at 12 grains. No reliable data yet on the new carbon ones used by Easton on the Kilo tent.
Unlike many other brands that try to confuse, the Victory 300 designation means a spine (stiffness) of .3" deflection under a standard weight and span. The Easton .344 alloy pole happens to be just the right inner diameter to use as an external ferrule, and is available from Quest, and possibly TarpTent (Scarp cross poles). Of course, the weight of shock cord, ferrules and tips must be included. The most recent pole set I made of Victories was 9.5 oz total for a total of 26 running feet.
Will be using the V6 300's for dome poles this summer, often above timberline, and will report on how they work in real conditions, as distinguished from improvised break tests at home. Will set up the tent at home and give it a good drubbing before leaving, just to make sure the Victories are as good as I expect.
