Jiraiya being one of the legendary sannin... I think when Naruto was training with Jiraiya it would've been better if it was Jiraiya that introduced the kaga bunshin training. He wouldn't have to have learned any new jutsus, but at least he'd be stronger, smarter, and realize his kage bunshins can be used as an analyzing tactic.

Then all Kakashi would have to have taught him would be the elements and stuff.
