Momoshiki wasnt fast enough to outspeed his shield of sand, as gaara was able to catch him with his sand, but why did his shield not activate when he got wrapped in Hair? This is a tricky part to justify. I think it is basically just for plot purposes that we see people or things (on rare occasions)that shouldn't be fast enough to out speed Gaara's defense, get through.

My theory is that in those instances in the series, was that a weak point of the Sand Shield's automatic defense could be that, if Gaara is already using the Sand under his control either for offense or for a defense he already set up, it may interfere with the speed or reaction time of the Karura-willed defense? If that makes sense?...it's a bit far fetched of a theory if you ask me, but not coming up with something makes it seem like the creators are working against their own work.
