  We account for dynamical spin effects in the holographic light-front
wavefunction of the pion in order to predict its mean charge radius, decay
constant, spacelike electromagnetic form factor, twist-2 Distribution Amplitude
and the photon-to-pion transition form factor. Using a universal fundamental
AdS/QCD scale of 523 MeV and a constituent quark mass of 330 MeV, we find a
remarkable improvement in describing all observables.
