That one touch would probably never land on Lee though... even if it did, he'd probably miss. I mean, he did miss the first time on Naruto, and he wasn't really even moving.
On a side note: Theoretically, that Kaiten ability should burn up a massive amount of chakra.
- It is said that even Jounins can only release a small amount of chakra from their hands or whatever, meaning only a small amount of chakra is enough to get the job done. Whereas Neji releases a lot of chakra from all over his over his body. Seeing as it's a defensive ability, it sounds like a desperation move that is very limited as of how many times it can be used. If this is the case, then it could be a fitting counter for Lee's gates.

I think a fight between Lee and Neji would be pretty even. I'm routing for Lee though
