Nobody said he will attack with clones...clones are supposed to be a distraction, which won't work in Neji case...and he won't spin forever I know...that means Neji will attack, and he is faster than Shino, so he will be able to position himself to land hits...
Anyways, why u all always think shino is only gonna attack with Bug clones?! knowing fully what the kaiten heavenly spin can do.... One must be retarded to be like that. He saw the jutsu, he knows what it can do, Plyr88 Has told various ways in which that technique can be beaten, Swarm of bugs wave by wave and attacks, Neji CANT spin Forever.
Shino just has to wait or easily calculate the time it takes neji to stop spinning and a good swarm of kunais or explosive tagseals can best him, also i already stated that bugs can come from beneath him, and neji would never shake them of with kaiten if they are in the middle, has one of u though about hurricanes and their eye?
