I really cannot bring myself to whack anything with a mallet or hammer!
An entirely understandable sentiment, but I would urge you to consider what you would do if you had a puncture whilst on a remote lane in France well out of cell phone range and you didn't want to have to wait for recovery? It's happened to me twice. Those nuts do up flippin' tight, and some sort of shock to reach the breakaway torque is going to be needed. You are not actually hitting the car after all if you use the spanner.
The eared spinners of course were specifically designed to be directly clouted with a lead hammer and personally I like a bit of patina, to my mind it's all about the traditional appeal of Morgans.
