But I've been thinking about your post as well as those of brianb11213 above and wonder whether the view from a wedge and Baader film converge as apertures increase.

Not in my experience. Visually, the wedge has a slight edge over film irrespective of aperture (when used on the same tube). Maybe some batches of solar film are better than others ... or maybe some users of solar film have neglected to remove the translucent protective layer when making the filter up, this will definitely cause the poor contrast that some users report.
