It makes total sense to use blends especially for milk based espresso drinks, it’s so hard to pick out specific notes or fully appreciate them when diluting the coffee.
For straight filter brews I imagine you’ll notice the SO differences quite quickly, I doubt you’ll need much training as it’ll be quite apparent once you get it dialled in. It’s certainly worth a go, if you don’t think it’s worth the extra price then you can always revert back.
