Which spring should you use in the Normcore V4 (15lb, 25lb, or 30lb)?

The factory-installed 25lb (approx 11.3kg) spring is optimal for 90% of home espresso setups. It fully compresses the coffee bed without strain. The 15lb spring is ideal for lighter roasts or gentle tamping, while the 30lb spring provides maximum firmness.

Which Normcore V4 tamper size fits Sage / Breville espresso machines?

For 54mm Sage and Breville machines (Bambino, Bambino Plus, Barista Express, Duo Temp Pro, Infuser), select the 53.5mm or 54mm version. For standard commercial/prosumer machines (Gaggia, E61), choose 58.5mm.
