Herc isnt "bigger" enough for me. I want my Devs to be noticeably (but not ridiculously) bigger than the other combiners. Its the reason I'm not satisfied with any Menasor offering... too small, too ugly, or in the case of Havoc, just enough "too big" to fit with my other combiners. But its all personal tastes... I really did love Heavy Labor from this set. And admittedly GB's Bonecrusher blade conversion method for robot mode is super fiddly, and I wish they would have done something more like TFC's. And the gestalt-gun idea (a la Herc and Havoc) is something I love. GB doesnt have that either... not perfect, but still preferred.
