  We continue explorations of deformed Abrikosov-Nielsen-Olesen (ANO) strings,
with non-Abelian moduli on the world sheet. In a simple model with an extra
field we find classically stable ANO and non-Abelian strings. The tension of
the latter is a few percent lower than the tension of the ANO string. Then we
calculate the interpolating field configuration. Once the kink mass $M_k$ and
the difference of tensions $\Delta T$ are found we calculate the decay rate of
the ANO string with a higher tension ("false vacuum") into the non-Abelian
string with the lower tension ("genuine vacuum") through the "bubble" formation
in the quasiclassical approximation.
