Just wondering how youhave the correct spine onarrows that you are planning on adding unknown quantities of weight to?Wouldn't adding50+ grains of weight change the numbers a bit? Just thinking because I plan on doing something similar by gettingoverspined arrows a few incheslonger (2 in)then neccessary and am also planning on adding weight/points until I see whats best.Just getting a longbow setup myself and thought the weight really mattered but may be not as much as i think from what seems to be working for you. take care.
