OK, I guess the higher is the integration the harder is to do it manually. Also I suppose it takes much more time if you have a largish volume than doing it with the SM paste. Anyway, that description is very interesting and may try it at some point. The only thing which I have to keep in my mind is that the Pb poisoning is not just about licking my fingers full of with solder paste :-) but to inhale it when baking the circuit.
