That link just re-inforces my view that rather than mess about with a smaller front or bigger rear sprocket, why not just choose to ride around in one gear lower - then you have the response you desire - all you're doing by changing the sprockets is raising the RPM's for any given speed - just the same as riding around in a lower gear for any given road speed. It's the riders choice that makes the difference.
Personally, I always put a larger sprocket on the front of my in-line fours, to give a more relaxed feel to motorway cruising, but when I'm riding either on track, or on non-motorway's I always ride by engine feel and sound, not by what gear I'm in. The police and most riding schools teach you to ride with the engine revs matching the response you want/need for traffic and road conditions - if you do that you don't need to mess about with smaller front or larger rear sprockets.
Just my opinion and I know many others disagree - but I've always found it works for me.
