I'm glad to hear the bulk download is working for you. In general, there isn't a way to get pre-made raster files because we generate them as custom requests. So, state-wide pre-made rasters just don't exist. However, there are data sets where DEMs were made as part of the original deliverable and we may look into putting those out with the LAZ files. That will be much more hit or miss depending on what we have. We also believe that the USGS NED should be the standard raster version and want to avoid generating a competing standard.
We would be very interested in adding the 2006 CT data. I'll send you an email.
