H alpha filters

A question on filters and solar observing. We know that the Coronado PST gives superb views of the sun, particularly it's structure and prominences. Given that the PST allows only h alpha wavelengths through, has anyone tried an h aplha EP filter in combination with solar film to see if the same effect occurs.

Note: Before anyone jumps in, I am not suggesting using the h aplha EP filter without a suitable (baader or 1000oaks film etc) solar filter on the front of the OTA.
