The Arrow Dynamics shafts lack spine consistency around the shaft. They are just not as precision made as some most carbon shafts. So I usually spine them and turn all the stiff sides to whatever I think the preferred direction is. And that helps but still you get some shafts that don't act like the others.
Here is something you might want to throw into the mix for tuning your Arrow Dynamic shafts. (Or for those that threw them in the corner in frustration).
Assuming the shaft and point weight is pretty closely matched for your bow to start with. Use the standard shaft for heavy draw weights and the AD lite for lighter draw weights.
Get you bare shaft (capped or wrapped if you do that) and put in the point weight you want use.
Now shoot the bare shaft, 3-4 times then rotate it on the nock a 1/4 or 1/8 turn and shoot again. Keep doing that all the way around the shaft 2 or 3 times. You will find the best flight. It can vary the whole way from weak to stiff. The best each shaft shoots does not correspond with my previous stiff side markings.
Do that to 3 shafts then fletch and see if they perform much better.
