I was wondering if the Sgt. savge FIGURES are as easy to take apart as the ARAH line. Does any have any of these and if so what scale are they and how do they compare to the new and old sculpt Joes. Just wondering because I wanted to use the arms & heads for customs.

I think they're too big for even new sculpt Joes.

No. They have no back screw, glued together. The design isn't the same. I forget their exact size, something like 4 1/2" I think. Not quite 5"

They're too big for the line. I own most of them and like them, but they're just not G.I.Joe in my book.
