I've shaved with E's, G's, and I's, and found them all to be pretty comparable in terms of mildness (or lack thereof).
How do the L's and N's compare? For that matter, where on the Adjustable's scale would the G comparatively be?
I can just barely differentiate between the levels of aggressiveness comparing a G with an I. My own E & G seem the same, as do my own I & J Schicks. Whatever the bright yellow one is (M or N ?), it's a toy compared to the other four, it's so difficult to cut whiskers with it. I don't have any adjustable type of Injector.
