well, doesnt look like too many people are in favor of the
favorite customs theme 
how about a theme week dedicated to favorite scenes
in the first two GIJoe Movies?
GIJoe A Real American Hero and
Revenge of Cobra?
example
like the scene of GungHo, Lady Jaye & Shipwreck escaping from the Temple of Doom
holding the fragment of the weather dominator while the temple collapses
or
the fight of Duke & Snake Eyes vs the Cobra Troopers & Seegies on top
of the truck to protect the other fragment of the WD at the beginning of R.O.C.
etc
