"The point I'm trying to make is what we see in the cartoon/comic is done to impress or simply to make the fiction work."
OMG this is just what I was thinking without having the words to express it! GET OUTTA MAH HEAD CHARLES!
I think the best solution being, the Gestalts shouldn't be "size compared" versus G1 cartoon, or comic, or even in relation to each other...but by relation of their alt modes
For example...Herc was done so well because their alt modes, as construction vehicles, matched up more or less okay with, say, Henkei Prime and such (not so much with Weapon/Medical specalist but I am willing to forgive them because they ROCK). Bruticus Maximus, however, was a total fail (although made alot cooler thanks to FP) because the alt modes were so scrimpy (Swindle's alt mode hummer versus, say, Jazz for instance)...and the tiny little excuse for a helicopter or shuttle that was Blast Off and Vortex.
That being said, if someone made a Menasor based on car alts about the size of, say, classics Sunstreaker, he would make an excellent sized Gestalt. As far as Uranus goes, I always thought I would be happy with an Aerialbots team that was roughly on par with the classic seeker molds (although they themselves should have been a tad larger, comparatively)...and it looks like TFC might be holding to that.
I think collectively we should stop nitpicking all of the 3P'ers, since they have put out some wonderfully awesome combiner teams as a whole, even giving us multiple brands from which to choose the same teams from (Herc vs. Giant). The REAL problem, of course, lies in the fact that a lot of our favorite TF's have never been scaled well to begin with. Most of the Autobots I have collected so far seem pretty close (comparing guys like OP, Sunstreaker, Tracks, Weapons and Medical Specialist), with only a few notable exceptions (such as the Seeker molds or the Superion/Bruticus Maximus teams being either somewhat or just plain way too small, individually).
As a matter of fact, now that I think about it...I see some anti-Decepticon conspiracy going on here! Seekers, Combaticons, and even our options for, say, Reflector were woefully small...whats with all the D-con hate?
