What are the undersized fundamentals available?
You mean fundaMETALS.
dv888, Tactic, Hectic
Lunatic also. 
They all look undersized to me. I have yet to see a larger one.
Is the California 2010 undersized as well?
I think it’s slightly undersized.
All YYF Fundametals are fully undersized, except the '10 California which is about medium size(think K-os and SFHG).
chaotic is also very good

Yeah, those are discontinued. All of the Yoyofactory FundaMETALS are slightly undersized.
