  We begin the systematic study of knot polynomials for the twist satellites of
a knot, when its strand is substituted by a 2-strand twist knot. This is a
generalization of cabling (torus satellites), when the substitute of the strand
was a torus knot. We describe a general decomposition of satellite's colored
HOMFLY in those of the original knot, where contributing are adjoint and other
representations from the "$E_8$-sector", what makes the story closely related
to Vogel's universality. We also point out a problem with lifting the
decomposition rule to the level of superpolynomials -- it looks like such rule,
if any, should be different for positive and negative twistings.
