It shipped with a tuck of Derby Extras. Last time I tried them I actually liked 'em. Having said that, I do have some Nacets and think I will take your suggestion to heart and use one tomorrow!
Yep, against my R41 (chattery) and fatips (sometimes wonky) it was solid and classy.I have always gotten great shaves with my RR SLOC and I think it is among the best bargains in DE shaving. Among its many positive attributes is excellent blade clamping and perfect blade alignment.
