Last year I was shooting Sirius Vulcan 300s at about 755gr. Bow was clocking about 200fps with the ez v sight. Up graded some this year. Shooting a liitle faster. So my test kit was liking 250s out of it. Gonna build something around 650-700. I like the Sirius Apollo's because they are available as shafts, ethics inserts and light weight. Good price for one stop shopping. I like the victory shafts, but hard to get bare shaft to build my own. 250s are hard to find. Before I order, any one have something else they recommend? Or where I can get victory bare shafts?
