When my wife and I started bow hunting in 2013 we started off with Easton Bloodlines at the recommendation from the dude at Sportsman's Warehouse and have been using them ever since. Between the 2 of us we have killed 4 nice, mature muley bucks and we have been nothing but satisfied with them. For the price of a half dozen of my Easton Bloodlines you can get a full dozen of the Easton Gamegetters (some Cletus must have been up thinking hard all night to come up with that name). I love that value! I have been doing a lot of reading on ArcheryTalk and other places and it looks like a lot of guys think the old aluminums are every bit as good as the carbons of today. I'm not a speed freak, and I will take a heavier arrow any day. I've heard a lot of good reviews about this particular aluminum. Has anyone here used them and if so, what is your opinion on them? The only problem I could see is the whisker biscuit I currently have is set up for a thinner diameter carbon shaft I believe. Anyone have any idea how much the 330 spine one's would weigh? I don't know how to determine how much aluminum arrows weigh since they don't have a listed gpi like carbon arrows do.
