Jim from your Mapdot you look like you are a couple hrs west of us.  If you would like you could come ride with us this fall and see 3 Macdons in use, 25'ridged, 30'flexdraper, 36'flexdraper.  I personally hate having my crop threshed in the header would prefer it to happen in the combine.  The MD draper will cut as low as a traditional flex head and save beans from reel shatter.
