The finale at the NW Pyro demo was very cool and a more traditional sky-puke style finale, the other main option is larger numbers of a single item or series of items, as in the Victory Fireworks demo. This one is a huge number of 200g Red and Silver Razzle, followed by 200g Gold Brocade Bash, then 500g Gold Fever (all PYK).
This video was recently uploaded by QMAN on PyroU here, but I thought it was pretty cool, so I'm throwing it up on my blog too. Description: "This is 6 Atomic Funks setup in sets of 3. This was fired are Johnny Lema's Customer Appreciation night in August of 08."
Haven't posted one of these is a while... I don't look through Freakpyromaniacs that much because of the language barrier, but there is always a lot of cool stuff, like this front of 13 consumer cakes at a consumer fireworks demo in the Netherlands. I don't know the exact numbers, but I seem to remember that they have a max tube diameter of an inch or so (comparable to a standard 200g cake in the US). On the other hand, they can have harder breaks. I still think we have it pretty good in the US, but they have a lot of nice stuff too.
Big Fireworks is a growing name in 1.4G and has been pretty nice to PyroU as well. They apparently put on quite a demo each year, here (.wmv) is the finale (thanks to PyroU member grdodd for the video).
