Spine align is a waste of time, IMOIn your experience, are the "spine aligned" arrows not actually spine aligned? I've read on different forums that spine aligned arrows are often/usually not actually aligned so I'm trying to figure out if spending the $ on "spine aligned" arrows is worth it or not
Best practice is to number your arrows and log your groups at longer range.
If you have an arrow that is consistently not grouping, then twist the nok or reflect if necessary.
Now, you have to be able to shoot well enough to determine if its actually the arrow.....
