I agree that LM USA is terrific. But perhaps you haven't done business with Chris Coffee. Their support is top-notch.

Great news! Can not wait for the retrofit kit!

I can consistently and easily hit 0-9 bars and anywhere in between with my existing Strada mod. It took about a month of playing with before I got good at it, and it still requires me to focus when I'm pulling a shot. From what I've been told by LM, this new conical valve is a lot less sensitive. There's probably a quicker learning curve associated with that, but essentially the same functionality.

I agree with the customer support! VERY responsive and helpful!

As for the Strada mod, from what I recall in reading on this, the range from where you can adjust the pressure is very little, which in turn would make it more sensitive. Maybe the conical gives a wider area for adjustment making it less sensitive?

Yes, this is exactly what it does and my opinion is that they are just patching what it should of done in the first place. They should give retrofit kits for Strada MP (and Shot Brewers) for free!

always the same question from me, if this is plumbed, with the better control, do people think youll be able to make those super long preinfused slayer shots, or do you need the "flow profiling" instead of the "pressure profiling"

you could do this with the old and new versions. The problem is that regulating the flowrate of the preinfusion is manual, as described above.

Where a slayer has 2 waterflow paths. one is restricted by an adjustable needle valve (that is not adjusted during a shot) and another is "unrestricted"
Then the paddle switches between the 2 paths to enable/disable the special preinfusion flow rate

LM MP has a manual (now conical) valve that is opening and closing and can achieve both of those flow rates and everything in between and more.
With the new model, it should be easier to "graduate" the paddle by measuring and putting a little sticker on the group head that indicates "This position is 50 g/min". Then you can move the paddle to that position at the beginning of a shot, wait some amount of time, then go to full to simulate the slayer preinfusion.

Also, it doesnt need to be plumbed for this anymore according to the press release.

just curious, if you move the paddle the smallest amount to start the extraction, what kind of flow rate (grams per second) would it have?

it goes from 0 to full speed (regulated by whatever gicleur you have)
I can get it to produce a few drops per second.
Quick video to demonstrate.

super helpful explanation, so when you move the slayer paddle past the preinfusion position (where the flow rate is fixed by the needle valve adjustment) aren't all the other adjustments manual as well

it seems in principle that if you correctly layout your start points, you can get to the same place as you might with the slayer or the strada mp

whats the size of the gicleur that comes in the gs3 these days, is that what you have in your machine or something smaller
