Which of the Leachies are the largest...

[Starforce2]

besides the grand terra itself? Theres the henkel, isle of pines, isle E and Nuu Ana. Are is island variants all roughly the same size? I am curious to know how large my isle of pines will get. If anyone knows what ages they must be to be sexed that'd be helpful too. Mine is apparently too young so I don't know what it is yet. It's larger than either of my cresteds or gargoyle, though.
