We introduced a generalized Wilson line gauge link that reproduces both
staple and near straight links in different limits. We then studied the
gauge-invariant bi-local orbital angular momentum operator with such a general
gauge link, in the framework of Chen et. al. decomposition of gauge fields. At
the appropriate combination of limits, the operator reproduces both
Jaffe-Manohar and Ji's operator structure and offers a continuous analytical
interpolation between the two in the small-x limit. We also studied the
potential OAM which is defined as the difference between the two, and how it
depends on the geometry or orientation of the gauge links
