I thought this might be an interesting conversation.
Which is more important to you, the "Durability" or the "Detail" of a custom figure?
When I say "Durability" I really mean factory quality - it can be played with. The parts don't pop in and out easily, you're not afraid of breaking anything ultra-fragile, all of the joints move properly, etc etc.
"Detail" means much that the figure is more a "work of art" for lack of a better term. Articulation might be sacrificed for better details; parts might be broken off easily if "normally" played with, etc.
Personally, I almost always go for durability - I want these figures to be like what I would have played with when I was 7 or 8...or 9... or 23...
I try to keep my figures as close to "factory" in that sense as I can; sometimes it means that I am unable to use a certain part or I have to go about making the figure in a different way, but overall I think it's worth it.
I'm not really sure why I go about doing that, but what do you guys do?
