WM Rambler as a second plane?
The Rambler 40 was reviewed quite favorably a while back. You would be going from a flatbottomed trainer to a symetrical AND low wing craft at the same time though. They said it was such a sweet flying plane that this should not be a problem. Personally I like the Rambler 30 and I will probably put an OS 32 in one. No retracts on that one.
