[CTPP] TAZ-TAZ Flow Matrix

Hi All, Based on your experiences with the 20/20 software so far, what would be the best (meaning fastest) way to obtain a TAZ-TAZ O/D matrix for all TAZ's in Weber, Davis, Salt Lake and Utah Counties. I want all trips originating and ending in those 4 counties. Anyone care to put forward the fastest way of doing a query such as this? Ultimately, I will be processing the data for all metro regions in matlab or python, so it would be great if the data came in a 4 column table: origin, destination, flow, MOE. For the 2000 data, I used to just download the flat files state by state. Is this option no longer available for the 5-year ACS data?
