while comparing direct to ares V is pretty fair you could maybe stop using those cursed colors on a white background. you are causing me headhaches.

The real difference between direct and the constellation ares V is that the direct people are advocating for a different 2 launch architecture than what was chosen by NASA.
thing is. if you drop Ares I and go straight for Ares V you have already done the switch-over to the direct architecture.
with single launch Apollo style excursion type landings, and a 2 launch mobile base type mission for extended stays.
I have the feeling that that was always a fall back option for the constellation program. also. the Ares I was more meant to give a crew only launch option that would be unaffected by mission type. it would basically mean that all missions would use LEO as a staging area and start point.

I prefer the flexibility that having a separate launcher for the crew allows in mission types. it allows one to freely use a 2 or more launch assembly sequence followed by a separate CEV Launch just prior to departure from LEO.
