Marker Alpinist U-Springs

[dangur]

I am seeing conflicting information about the springs that come stock in the various models of Marker Alpinist AT bindings, and the various release values (let's call it approximate DIN) of the different spring options.

Here we are told that the Alpinist 12 comes with the Medium spring. Also, the Medium spring is ~8 and the Heavy is ~10 release value.

Other sources say that the Alpinist 12 comes with the Heavy spring. They assume that the Heavy Spring's RV is ~12.

Does anybody know the answers to these questions?
1. Which spring comes stock on the Alpinist 12?
2. What is the approximate release value of the various Alpinist springs?

IIRC the early models might have been different but for 20/21 production this is correct:

The Alpinist 12's come with hard (10'ish) U-bows.
The Alpinist 9's come with medium (8'ish) U-bows.
The Alpinist 8 comes with soft (6'ish) U-bows.
All of the U-bows are available seperately.

Very belated thanks to Spyderjon.

Now a question about Alpinist toe pieces:

Are the toe pieces different for the 8, 9, and 12? Specifically, are the springs softer/firmer?
