The number of holes of course don't determine velocity and flow rate. I had a four hole one for my Bezzera that would froth 600 mls of milk in 15 seconds. It flows a lot quicker than the four holed one on the Wega.

Yes, they are optional accessories (which I had purchased for curiosity sake, along with LM GB5 wand and Sproline Foam Knife 1 + Vortex). They have a newly designed 2-hole steam tip where the holes are oriented in the same direction to spin the milk easier. I've had the best results with the new 2-hole tip as well as the 4-hole, but it still doesn't quite match the boutique cafes using a commercial machine. I have no problems attaining results with the LM linea classic 3-group and its stock 4-hole tip though.Originally posted by samuellaw178 View PostIf the pressure drop is less it'd be an easier learning curve for beginners...not everyone starts out as a barista champion
Didn't Rocket come with a set of steam tips (or are they extra accessories)?
Unlike your wega however, the Rocket definitely does not take anywhere near as long as 15 seconds to recover from 0.7BAR.

It is just physics. If the boiler is the same size and the heater element is the same wattage, it will take the same time. It isn't a brand or prestige thing. It is just physics. My 20 year old Bezzera will kill anything with a 2L boiler as the boiler is twice the size and twice the heating elements.Originally posted by blazer78 View PostYes, they are optional accessories (which I had purchased for curiosity sake, along with LM GB5 wand and Sproline Foam Knife 1 + Vortex).

Edit: It could be the rate of draw down of the boiler too, steam flow affecting it too.

Just to add to this old post.
I've recently replaced the stock 2 hole to a aftermarekt 4 hole on my giotto. The steam power is now almost the double which I absolutely love and much easier for me to steam good milk as it's a closer power as commercial machines I use at work.
The pressure on my giotto does indeed drop to about 0.7bar from 1.1ish from about 5 seconds into the steaming and it is annoying. However, I still think it is far superior than the stock 2 hole and the results speak for itself.
