  We propose a model with a U(1)_A x U(1)_B gauge symmetry which contains
topological strings carrying magnetic flux under each of the U(1)s. By
calculating the tension of the first few low energy strings we show that bound
states, containing flux under each of the U(1)s, are stable against decay to
their constituents of lower winding number. As the model contains only Abelian
gauge symmetries this model provides a pragmatic solution to the numerical
modelling of cosmic-superstrings. Whilst these defects do not satisfy a BPS
bound we argue that they bear sufficient similarities to warrant such a study.
