Better remolds FTW. I don't like the simplification factor of a lot of today's TFs, but the smaller size doesn't really bother me.
A good remold can look and feel like a whole different TF, and HTT seem to be getting better at it as time goes on.
It doesn't affect my collecting habits all that much personally, since I have a not-very-strict/lots-of-exceptions collecting rule about trying to get different molds for different characters. Still, it allows them to cover a lot more ground and boosts my chances of getting a character I'd like to have in my collection.
