4mm VS 5mm VS 6mm

[SippyCup]

I’ve gone from 80# to 70# draw weight and need to get some softer spined arrows. I only have experience with 6mm and 5mm arrows, and honestly there isn’t a noticeable difference between the two. I keep hearing that 4mm buck the wind better but I cannot find any hard data proving the performance increase. Something comparable to a ballistic chart similar to the 6.5 CM to a 308 would be sweet to look at.
Has anyone found any data like this?
