In which case I would disagree with you. A signature technique is one that's used so much that it becomes associated with that person. For Naruto that would be the shadow clone jutsu, since he's consistently spammed that throughout the series. There's also the fact that a lot of the time he needs shadow clones in order to perform a rasengan or rasenshuriken.

Other examples of signature techniques not being the strongest: Minato known for FTG, Shisui known for Body Flicker, Tobi for Kamui, Pain (specifically Deva Path) for Shinra Tensei, Gaara for Sand Burial, Choji for Expansion Jutsu, and that's all I can think of at the moment.
