So, Paulbot, Iceburn and I were talking about whether we were interested in Acid Storm or not, and Paulbot mentioned that he read somewhere that it used the Skywarp mold as opposed to the Starscream mold. He then followed up with the source:

Other Notes: This is actually a redeco of the Skywarp version of the
mold, not the original Starscream, but I've listed changes in plastic colors
relative to Starscream since more people are likely to have that one. The
difference is mainly in the air intakes, which have a shallower interior
angle on Starscream than on Skywarp or Acid Storm.
Unfortunately, all my Starscreams have been donated to Classics LioKaiser projects so I can't compare. What say all of you?
