Oh no problem, I love a good debate =) *pushes up his metaphorical geek glasses to his nose*

True Neji can see, but sight only goes so far, quite literally. And you have to know what you're looking for. If Neji can see them, he couldn't see through Naruto's shadow replications. Akamaru, however, would be able to sniff out the real one without second guessing it. Something that Neji, and Kiba had trouble doing.

No prolly the Sand Jounin wouldn't challenge them to a survival contest, but I think they're in a lot more trouble if a Sand Jounin challenges them to more than a Survival contest. Another set of fighting hands however, that'd come in useful. Everyteam does have their flaw., Sasuke definitely has them too. Relies too much on flashy/showy chidori to get jobs done. He's similar to Neji in that he can get horse blinders on when it comes to fighting.

Sight vs. Smell isn't the same job, infact they're two completely opposite senses althogether. Together however, I think they'd be a lethal combination. That on the same team with the tacatics and experience of Shika and Kakashi made that combination on Ninjas the best.
