Don't take this wrong, but I doubt that you are able to tell.
The internet is great but remember that most is opinion. Archery is a mental game so if you think it makes a difference than it does for you.

I remember being at LAS when a guy returned broadheads because they weighed 103 grains on his scale. Not the 100 indicated on the pack. WTH?
With a very good reloading scale I find that carbon arrow shafts vary that much before (3 grains) you start to assemble them.
