Yes, I think you are right to move Amie-Thistle. I have done many planet missions and enjoy most planets and moons that I land on. I usually take a rover to get as much out of the mission as possible. Another Europa type planet like Floorite would be cool, or an incredibly cratered planet like Pock, but it is probably more difficult to create... This is a pic from a Pock mission. A very cool planet. Opal looks to be a challenge. I need to go there! http://i950.photobucket.com/albums/ad343/Larry_M/KSP2014-03-0417-25-22-86.jpg
