Daniel, cane is easy to straighten with a little heat. It's easier if you do it in sessions. Maybe straighten in between the nodes one day, then the nodes another time and do a final touch up after you mount the points. I like to spin them to see how straight they are.
These haven't been spine checked but I will as soon as I make a tester. They shoot best from my bows around 55-60#. As for the weight, they run from around 480 to 580 grains.
