It takes a LOT of "trial and error" to find a steaming technique that works. It seems most people play with pitchers, tips and wand position for several months, until they finally find something that works.
For me, I found the best results with the stock 4 hole tip (the new 4 hole is a bit too slow for me) and the tapered 15 oz pitcher. I keep the tip exactly in the middle and perfectly steady. I simply sink it after 4 seconds at the surface and let it mix the bubbles for 21 seconds (for 6 oz of milk). It seems the less movement the better...and getting a toroid swirl works best.
Other have found other techniques that work, but for me, this is what I need for good latte art.
I used to think the Vivaldi was a poor steamer, but after buying my Cremina, I now consider it one of the better ones. The Cremina is MANY times harder.
Patience. That's the key. It will come.
