Ah, Mike Reese (51 ashton) has tried to educate me on double clutching gear-shifting. I had first tried to learn this double de-clutching in Britain almost 40 years ago. If/when I put a Clark 5-speed (w/overdrive 5th gear) in my COE, I'll have to learn/master the technique.
I'll be interested in reading how people try to describe this supposedly simple procedure (simple once you have learnt it).
