In this note we expand on our previous study of the implications of LEP1 results for future colliders. We extend the effective operator-based analysis of De R\'ujula et al. to a larger symmetry group, and show at which cost their expectations can be relaxed. Of particular interest to experiment is a rephrasing of our previous results in terms of the Renard et al. parametrization for the gauge boson self-couplings (slightly extended to include $\delta g_{ \gamma}$). We suggest the use of a ($\delta g_{ \gamma}$, $\delta g_{ Z}$) plot to confront the expectations of various models.
