Only the relatively new Avatar grenades from Redwolf Airsoft are missing, for the rest all popular items (as far as we know) are tested with a slowmotion camera at 1000 frames per second. GRENADE TORNADO, HAKKOTSU THUNDER, STORM 360, GZ TYPHOON, KIMERA, NUKE, NOVA48, CYCLONE and the PROTO RAGE IMPACT. Cool footage and decide upon the winner yourself!
