Interesting, the Specs say
"Even less drag than the VT, thanks to the added stiffness of Aluula, which has allowed further reduction of the leading edge diameter by an extra 5%... "
and the V13 or VT is smaller L/E than the V12. Looks like they've been very busy trying to maximize the aluula for their biggest jumping kite. Bring on the demo's already 
Has anyone been able to demo the new standard edge vt compared to the ultra version
