I was shooting the Sportsmans labeled Vital Impact arrow for 6 years, at $40 for 6 arrows. I was talked into going to a spendy arrow to improve my performance, which already was expensive due to breaking arrows from tight groups.
I honestly had no visible group change at ranges from 10-60 yards, but I cried more when I broke an arrow as they cost me $90 for 6 of the Blue Streak "Select" by Easton.
I am not falling for that again.... If the less expensive arrows group tight...they are what I will stick with.
The only difference at first is cheaper arrows are boxed bad and fletching vanes are often bent....but easy to change so it does not matter much there.
