I'm not sure if the lance was the only factor. Mind you that most of the Swedish infantry carried muskets, which was a direct result of the lack of enforcement of army regulations and standardisation amidst Swedish conscripts. This means unprotected musketeers had a very inflated role in early Swedish armies. In Kirkholm they not only lacked pike support, as I am informed, but also were very predictably unlucky when the Swedish cavalry attempted a Caracole at Polish horse and were routed in minutes of combat. Later pistol armed Swedish cavalry abandoned the caracolle and used more shock oriented formations to greater effect.
