When anyone mentions "use Young Link's projectiles", they mean all of his projectiles. The bow should be the least used projectile but still a good item all the same. The bow is just a quick snap that's not used for packing in great punches, but for a small stun And for a fully charged attack, sometimes. You can charge up a full bow shot by waiting by an edge and edgegaurdig with it. Or hit them with a run A attack, when they hit the ground, charge up the bow and then shoot them. The bow emits them on fire and bounces them up into the air which can be used for some small combos.
sh-B>run A=Is an effective combo to pull off.
or...
B>SHFFL'd nair=is also good.
The bow is not useless by any means whatsoever. It's also good for just keeping opponents backed-off. Shoot an arrow straight at them and then they'll want to sheild, the arrow hitting them causes stun on the sheild. Be creative and go up, grab em' or whatever. Just remember the bow is another handy dandy tool to add to Young Link's utility belt.
Ximrecuf, I want to see some Young Link vids soon.
