:-) I knew my Kamui assessment was a little off, since I didn't bother to search for several reference images. Luckily, it was never a crucial detail-
Thank you for the other size infos. Aside from having fix numbers now, they confirm my overall assessment of Kigai being the one closest to Sei in size (discounting the bear Kusanagi).

Do you by chance happen to have numbers for the CCD staff in X? I'm curious, whether or not my perception of size is skewed as much as my perception of age there. :-)
