With respect to scaling FRS to SHF, I feel FRS Zi-O and Faiz blend in quite well. Granted these are the only kits I own but the size of the helmets don't make the rest of the figure look like a bobble head. I would even go as far to say those helmets are about the same size of an SHF

These are well proportioned too, the only knock against them is they are noticeably taller than SHF. I've gotten around this by posing Zi-O in the far back row and putting Faiz in his trademark crouch position. Blends right in!

And as I've said many, many times here: FRS Faiz is a perfect placeholder for an SS release and is far better looking than that old crummy SHF
