Going to throw in my two cents here as well. In my opinion, G1 combiner teams were designed in a bygone era and should be enjoyed the way they are - rigid and bricklike in all their glory!

These upgrades are just an attempt to make them more articulated and therefore more like the classics/universe line - in essence; something they're not.

Plus, they're pretty expensive considering the very little aesthetic value they add to the figures.

I'm Kent Brockman...and that's My Two Cents.
