I just got 1/2 of my order from Lancaster Archery, 2314' s in X7 Eclipse. It seems that they are backordered on this shaft but I put togther what I had with 4 inch vanes and 100 grain glue in nibbs, 29 inches overall. Man they are dead on accurate and the weight is 452 grains, about what a heavy carbon weighs. I' m going to use them for indoor this winter and for 3D' s later on. My Pro 40 Dually in 60 pound and 29.5 inch draw puts them out there at 268 fps!!!
