A test kit is the perfect way to find the arrow shaft spine that's right for you. Micro-diameter Instinct® arrow shafts come in spines of 350, 400, 500, and 600. This test kit comes with one of each spine, allowing you to determine which spine is right for you.Wood grain carbon is a great way to meld the look of wood shafting with the strength of carbon. Black Eagle Arrows takes that a step further with the Instinct® arrow, one of the only woodgrain micro-diameter carbon arrow shafts on the market!The Micro-Diameter size (.165" inside diameter) of the Instinct® helps to offset the off-center design found in many longbows and recurves. It also gives you increased penetration and has less wind drift in flight.The straightness is checked on the full length of the extra-long 34" shaft. Straightness ± .005". Recommended field point: 9/32".Plus, Black Eagle has added their stainless steel outserts, adding 100 grains to the FOC (front of center) weight of the Instinct®. Please note, the Instinct® outsert adds ¾" to the overall length of the shaft. For example, if you order 30" shafts, they will be cut to 30" and the finished shaft with outsert installed will be 30¾" from the valley of the nock to the end of the insert.Each carbon arrow shaft is inspected for quality, and features a Duracoat wood grain overlay finish to allow for easy refletching and cresting.
