Agreed.
Just getting back into archery and finally decided it was time for a matched set of arrows, so plugged in the numbers for my Bear Custom Kodiak T/D, 50#@28" w/ 29" draw, then tweaked the settings for a matching arrow:
Carbon Express Heritage 150s cut to 31.5" w/ aluminum inserts, 100 grain points and 3 4" shield-cut feathers w/ Bohning birch bark arrow wraps --- I scrubbed off the writing w/ a 3M Scotch-Brite green pad and like the looks a lot.
They're shooting much better than the $3 Wal-Mart carbons I was using and I'm now confident that it's my skill or lack thereof placing the arrows on the target.
