The All new for 2015 Carbon Express BLU rz shafts are a dual spined shaft made to correct your broadheads quickly!

These BLU rz 350’s run 8.45 GPI and should allow me to shoot my new set up at 93 foot pounts of KE at 336 FPS with a 374 grain arrow… Sounds unfathomable, however, this lighter faster arrow hits harder than my old setup with a 426 grain arrow travelling at 295 FPS!
