Packed Primitives are so ace that it's hard to put into words. Polysoups are awesome also...
The only corner case niggle I've encountered with Packed Primitives so far is that you if you simulate them with a Pop Solver you need to manually update the primitive Transform intrinsic to reflect the changes to Orient etc. It's really trivial to fix, but it'd be nice if there was a toggle on the Pop solver to handle this for you.
