Good call on using a different nozzle. It worked much better but still had a little drizzle from the top of the can. I think it might be a combination of the nozzle and where it connects to the can.
I use an airbrush occasionally but use Testors cans for most of my painting. The basic white, black, flat black, etc. work pretty well for the most part. I've been using Tamiya spray more and more lately and as usual with anything Tamiya, it's great. A bit spendy though.
