I followed the mod where you replace the stock steam wand on the Alex Duetto II with a La Marzocco wand and a Sproline tip. Click Here (www.home-barista.com)
I went with the Sproline Foam Knife instead of the Vortex because the EP website says that foam knife is better for smaller volumes of milk. I'm trying to steam milk in a 12 oz pitcher with the foam knife on the LM wand.
The power of the steam coming out of the LM wand is much stronger than what comes out with the standard no-burn wand/ 4 hole tip that comes with the Alex II. The steam coming out of the foam knife tip looks like a narrow knife blade and the steam is really powerful. For example, on the standard wand/tip that comes with the Alex, I would steam milk with the steam valve wide open. With the foam knife and a 12 oz pitcher, if I open the valve full, the steam is so powerful and such a narrow stream, that the milk is just blasted out of the 12 oz pitcher.
So I barely open the steam valve to get the milk spinning in the pitcher, but I haven't been able to get any decent micro-foam. I've been steaming milk for a year now. I'm not an expert, but I'm not a complete rookie either. I was wondering if anyone else has gotten this combination of wand and tip to work successfully on an Alex Duetto II. Otherwise, I'm thinking about asking EP to swap the foam knife tip for the vortex tip.
Naively, I thought that making this change was going to quickly produce latte art quality milk, but it's only gotten worse. Any advice would be greatly appreciated.

I haven't pulled the trigger yet on this mod, but considered doing it a couple of times. I've found that whenever one changes their "system", whether it be a new wand, a different pitcher, a different steam tip, there's a learning curve to re-master the task of frothing. I suspect that as you work with it, you'll get better, as long as you're patient enough and analytical enough to figure out what changes you need to make in your technique/process.
One of the reasons I haven't done this mod is obvious...the cost. Another is that I've read a bunch of reviews of the Sproline tips where people say, yeah, they're great, but they don't really improve the quality of the milk much, if at all. Last reason is, I think removing the plastic tube from the Duetto (probably better to stick with this name, as Izzo makes an Alex HX machine; and an Alex Duetto DB machine) gives one plenty of improvment in steam quality - although you then have to buy a rubber sleeve or fabricate something else to insulate the now "burn me" wand.
. Always remember the most important thing is what ends up in your cup!

I went with the Vortex on mine and, while you still have to develop technique, the difference for me was evident very quickly. I'd spent 6 months or so working on my technique with the stock tip (both sleeved and unsleeved) and was still a ways away from being good and consistent. Within a few days of changing out to the Vortex the texture of my milk and my ability to consistently repeat results improved immensely.
