Why u should try bow 6?
Because bow 6 can shoot directly like gun shots. So fast to hit and u can steal tons of kills in squad games. If u get used to it, it is more easy to shoot than all other bows. (This valid for bow 4 too)
Main trick is, u should start reloading your arrow on air. Don't stay on your place when u pulling the bow. And get used to shooting with poosting. It is a bit more difficult shooting while u using your spear.
But, when a random bow 3 camper sniping u and focusing u from spawn don't use it.
