I'd peruse this research on High-MERV Filters and their impact on airflow and pressure instead of taking one HVAC technician's word for it: http://www.homeenergy.org/show/article/nav/issues/page/4/id/...

This graph of airflow vs. MERV rating isn't very conclusive in my mind: http://www.homeenergy.org/UserFiles/file/26-6_p34big(1).jpg

Granted there are about a million variables in all HVAC systems that could affect the results.

You know, I'm going probably believe the guy that replaces blower motors day in and day out for a living as opposed to the group that sets up a "test box". Sorry.
