I tried both, one hole is working the best IMHO as two holes gives too much air flow. Again try a few, first one will maybe not work right away, but when you get the right hole, you will love it!!
the tools:
I drill a hole with the 1.2 mm and then use the etching tools to make the hole wider, not deeper. Push the inside wool a little inwards so you will have the juice running better. good luck!!
