I say make both forms widely available and let people vote with their feet. How can people reject what they don't know or are unaware exists? The EF is one of the Church's best secrets. 

Obviously having 99% OF only parishes (many not celebrated reverently) isn't keeping people in the Church. If God uses the EF to keep/draw people to the Church, would that be a problem? Why did Mass attendance decline so much after the OF was imposed on Catholics?
