It appears that the newer, vspehre 7.0 course is 18 hours and athe 6.7 coures is 79 hours. The descriptions give the impression that they cover very similar material. Whats the length descrepancy ? Also will there be course files for the 7.0 coming. All in all they probaly are not that different correct? So if you want the more thorough course do the 6.7?
