Man, those pfizers always give me a serious skin rash!
I plan on grafting mine with itoigawa because even though they are strong growers, they don't really develop tight foliage.
As for the styling, I would try and see if you can wire some serious bends in that trunk. I think that would make it a lot more interesting. But I also acknowledge that the wood can be quite rigid and snappy compared to chinese junipers.
