I agree. You're WAY underspined. I shoot them for winter 3D for ease of pulling from McKenzie's. 27" long with 50gr tips and 60lbs is about the limit. 55lbs with 102gr nibs. I'd say they fly really fast but have to fly ugly. And I'd get the bow weighed to find out what it weighs. When shooting aluminum arrows a 10lb range is a lot of difference. .012 wall arrows are nice for speed but they do fall a bit short on durability, as Arthur said. You almost have to have your own straightener and keep after them. I think I'd go looking for some decent carbon arrows, too.
