my opinion
Strength does nothing because it cant oneshot with 10/10 atack
Travel speed does nothing on bow 3
Loading is very good but its only on a few arrows, so get loading speed on bow handle and tip
Stun isnt useful, its only good on bow 1, 4, 5
I'd recommend getting as much loading speed as possible on bow 3 if ur sniping, if u do mid range or close pvp i'd recommend strength cuz ur not fully charging ur hits
So the best arrow ist the fearless arrow / the one for 1040 / golden moon for 1460
