To be honest my brain hadnt ticked onto the idea or a two piece wing until you mentioned it.
I guess I got a tad hung up on trying to make the plane a more traditional plug in type configuration.

Regarding the reduction in size issue. As far as I am concerned any reduction in size will make the bird easier to store and transport.
It is a damn site easier to transport and store one big bit and 4 smaller bits ( tailplane and wing halfs) than two large bits.

I fly mostly on my own so anything that makes it easier is a bonus as far as I am concerned.
