Some may be like me and have an excessively heavy rifle. A 26" MTU contoured barrel is certainly NOT comfortable to carry at ~7 pounds (~15 pound rifle fully loaded). LRI has a neat page listing how much weight savings one can gain through fluting based on barrel contour and type of flutes he does.
