I checked and can now confirm that this is indeed correct.
My vote is unquestionably the Duo, but for Nordic light, with SSP Espresso burrs.
Ideally order the Duo with both burr carriers and if you don’t drink filter (or you have another grinder for it) then you can have one burr carrier with the stock Mazzer 151B burrs and the other burr carrier can house the SSP. Month on, month off, or whatever cycle works for you.
But definitely start with the stock burrs which for me, produce an inoffensive, smooth, well balance espresso. Personally it’s not a burr set that excites me (the stock 151F filter burrs do) but there are probably millions of people who love them and you may very well decide that they do the job admirably for your taste buds.
(Bear in mind that using non stock burrs will void your warranty.)
