The Super Poly Bridge script is a really excellent, if not slightly quirky, plugin.  I like it, and it definitely makes the creation of extruding loops much easier, once you figure out how to handle the script's interface and options.  By default, it only builds a guide spline with one vertex in the center, regardless if you choose "smooth" or "bezier".  I've found the results with just one vertex on the spline less than satisfactory, no matter what vertex type you use.  I would recommend immediately changing this to at least 3 vertices on your guide spline first, and possibly more, for better extrusion results.
