The longer he's been on my desk, I can almost buy into the head sculpt, but there's no getting around the arms and torso being subpar.
On the 12" front, I want the GB2 Winston in the 2pk which means I'd end up with a Peter. Supposedly, the Egon/Ray 2pk has a new head sculpt for Ray so I could be silly/crazy and round up a set that way and get all the cool gear. The problem there is, do you bother buying this stuff full price on the day of? And either way, it makes the Egon I have of no use to me.
I don't have plans yet. I broke the Proton Pack off of one for a picture I ended up not using, but I still have the other two. I considered swapping out the three extra sets of gloved hands (by virtue of having 3 Peters) with the rest of the 'Busters to get a "complete set" that way, but I'll prolly never do it.
