  We test various improved gauge actions which are made of linear combinations
of Wilson loops. We observe the restoration of rotational symmetry in the
static interquark potential already on coarse lattices as small as 6^3x12.
Furthermore, we study scaling and asymptotic scaling of the string tension with
a MCRG-improved action on 12^3x24 lattices. Preliminary results show that
scaling sets in at a ~ 0.3 fm.
