The Rambler was my second plane and its an awesome plane to fly, leave the retracts in the plane, she flies nice with them tucked in!
I think the SW and the 4* might be to slow of a plane (in my opinion) I have been flying for many years and still enjoy to take out my Rambler.
If you decide to buy it leave the retracts in it and build per manual, you will have allot of fun.
good luck on whatever your choice is
