I had a problem in years past with arrow weight, was going to buy kinetics but too much money at the time, for their weight there are others out there that weight the same. I opted for acc 3-71's and solved my problems, they may be a bit larger that the average shaft but at 9.92 grains per inch for me they are the perfect blend of speed , penetration and flat arrow flight out to 30yrds with one pin. Don't over look them, use the ones you have this year, and then think about change in the spring. Good luck and let us know what you decide.
