RE: Arrow Squaring?
With aluminum arrows you heated the glue up and moved the insert to square it up with the arrow. Also, with the slower bows it wasn't as big of an issue as the burners we have now. My aluminums hit the same field tip or broadhead. With carbons you can use the little plastic washers.
Today's bows seem to require a much higher degree of tuning at all aspects due to the increased speed and much shorter ATA. The bow I have now is probably close to 100 fps faster than my Whitetail legend I bought in 1990.
