Unsure. Like big axes. Give me a choice, and I'll get a big axe. Just ask anyone. True story.
I like the cheap and plentiful approach too - taking a 'bad' unit and using superior strategy to make it win also has appeal.
I suspect I'll go Saxon, and maybe convert some Dane Axes in for a switch (progressive campaign possibilities maybe - working throughh the time periods?)
The shear amount of models I'll be getting means that I can make a secondry force.
Saga Tapestry. Has an excellent suggestions blog on how to make loads of good looking armies with a few box sets - it suggests the Scotts but from what I can pick up, they are quite defensive, so don't want two defensive armies just looking at each other across the battlefield.
