So when he slightly over-cooks a wheely, he reaches for the front brake instead?

I'd pay money to watch that one.....
I find the rear very useful for slow speed work (under 5mph) where i have to get the bike around or between tight
testicles. I find i have enough to think about on the bars with throttle and clutch and pointing the bike where it needs to go, to even consider using the front brake as well (i'm not that clever). It also makes the bike feel a lot more stable, (though not so much an issue with a GS), as it doesn't make the front end dive, and the rear doesn't tend to be so "grabby" as the front...
