Malcolm I thought about it and if I were you I would put the Olympian out right away. A small TC plant should establish easily and grow fast in ground, and there is not much risk since it is easy to replace.

Figs are easily transplanted before they get very large so you can change your mind about what goes where later.

For example i dug 2 Stellas that were planted 2 years ago as year olds and the root system on them was larger than my Stella's in containers of the same age, even though the ones in ground were top killed the last 2 winters. The ones that have always been in containers will probably fruit for the first time at 3 years old, but I bet the two which were dug surpass them next season because they are growing very robustly.
