I personally like the acacius 2 considering the delta v and the fact that it is just AWESOME ! If it was a DSTO (double stage to orbit) and had a booster to help it on eve and tylo which would then be discarded. Jool however .... i tried to land on Jool but theres nowhere to land.Yesterday i found out that Jool is gas giant ... I think fart gas makes the R.A.P.I.E.R's explode.well time to keep trying.good luck Matt ! ps.im hungry
