I'd say he's making the job a lot harder than it needs to be. If you 
want to know what works well, look at what prototyping people do in 
industry. They use a soldering iron for most things. The use of solder 
cream is pretty much limited to robot assembly, as you can silk screen 
it onto the board.

Some kind of oven approach might work for BGAs, but on that page doesn't 
show any of those being used. The high temperature you need right under 
the package makes temperature control for BGA soldering tough.
