See, the Viking's lack of formation would actually help (if they avoided using the shield wall). They could charge all around the phalanx, which can only defend itself from one side, creating a one-on-one situation. The Spartans were trained from childhood, and the Vikings grew up in a hostile environment. With weaponry of equal quality, it might actually matter on the moral and number of the troops on the opposing sides.
While I agree with most of what you say, I have to point out that you need to go look up the term 'Phalanx', considering that it was specifically designed to deal with the envelopment/flanking tactics of cavalry.
As to who would win...
Very simply, one-on-one, the Vikings would, because their training was more oriented towards individual battles, whereas Spartans were trained from birth to be a part of a unit, and- frankly- performed poorly when isolated.
In a unit-to-unit battle, the Spartans would win, because, while the Vikings would throw themselves against the line piecemeal, the training of the Spartans dictates unity, maintaining cohesion, and not allowing the ranks to be broken. As a result, the Vikings would fling themselves one by one at the bristling spears of the Spartans, only to be speared in so many places that they bleed out before taking two additional steps.
And just FYI, I don't care how many 'magic mushrooms' you may have taken:
if you've sprayed every drop of blood you have all over the ground, your muscles simply will NOT WORK.
EDIT: and before ya'll go trying to tell me I'm wrong, go research the German Blitzkrieg in WWII. Its roots were founded in the observations the German High Command made about the tactics of Viking warriors-- namely, that they
knew that they were better one-on-one, but that they would get their butts kicked in a battle of massed formations; as a result, Viking tribal chiefs figured out tactics where they could present a series of combats with small numbers, as opposed to madly charging into massed formations. The German Wehrmacht adopted said tactics because they realized that, techonologically speaking, opposing forces could not match up with their troops on a one-to-one basis (particularly in re: tanks), but they very well might be able to resist via sheer weight of numbers.
