Ozark..., the matching weight is a trick I learned on here. Start out by seperating your cane according to mass weight. Once straightened you can sand/scrape off weight or use lead shot inside the cane to adjust weight up & down. Ionian,,a "master arrowsmith" who is on this site gets his cane arrows within 2 grains of each other and are pieces of art! As far as spine,,I no longer spine them, I just worry about matching weight,,another tip learned here. BamBooBender is another arrow "artist" here that I have learned from.
