On second thought, maybe flinging sticky web goop isn't such a bad idea. He can tell that the shields are closing in, trying to box him in and keep him from bouncing around so much, he figures. He doesn't want to try breaking them, since they are pretty handy for keeping the spectators safe, so what he does instead is hop up to stick to one of them, and then climb around to the other side of it like a weird spider.

He figures Gokudera can probably like flip it around at will or something, so he moves quickly, popping out from behind the shield to shoot a strand of web at that canon on Gokudera's arm
