[@OneWayOut] No, obviously, but being able to use only that jutsu while holding it is not a weakness, it's more like a limitation. A weakness for me is something that I can use/figure out to defeat that jutsu. I can't use that you are able to use only that jutsu against the jutsu to defeat it. That's especially true when that technique is a defensive shield technique with offensive capabilities. Either way, if wind is a weakness then that is fine.
