This is what caught my attention on the rareseeds web site.
From one of the reviews:

The large squash are sweet and firm. The flesh does
not get watery or bitter even when they are a foot
and a half long. I use the large ones in all the
same ways I use the small ones with no sacrifice of
flavor or texture. In addition, the large ones can
be sliced easily for grilling (and they are delicious
this way)
