I should also say if you are going to interpret "spin" in the old angular momentum way (http://en.wikipedia.org/wiki/Spin_(physics)) then you are essentially banking on a higgs effect (http://www.bun.kyoto-u.ac.jp/~suchii/Leib-Clk/higgs.html)
Which sort of equates to your energy hypothesis.
So you are betting on a higgs field Bill S or is it something different?
I am betting there will be no higgs field and far more controversial that fermions and bosons, like the old historic atom story of electrons, protons & nuetron found to be actually a 3D model of the one and only single anyon particle (
http://en.wikipedia.org/wiki/Anyon).
What I like about the anyon is it means no strange higgs effects and we only have one particle which is firmly linked in to quantum mechanics and wave/particle duality.
My problem with the standard model is QM is still stuck on the side like an ugly duckling with no real reason as to why it would exist other than it does and effects these fundemental particles.
So thats my wild guess at the moment :-)
