What gear when powering thru the hills?

[Ward P]

What gears do you use, how often do you change? when powering thru the hills?

Heading thru the Granya Gap the other day, I realised something.

I find when riding 1 up, the 'busa is grunty enough, that once I get into a windy section of a road, that I seldom, if ever change gears. With the newly acquired Gen2, which has a gear position indicator, I've now noticed, that I find that the bike just seems to end up in 4th when I approach the first in a series of tight corners. And once there, I don't change at all right through a windy section, even if that windy section is pretty long.
4th has plenty of legs for the few hundred metres between corners, yet will pull from fairly low revs provided you have kept good mid corner speed, but isn't too peaky out of the corners to have the back let go. The little I could lose in initial pull out of the corner just means that I can possibly hold off apply any braking for the next corner. For me, really heavy braking is a mind f*** on approaching a corner, it unsettles the bike and I can brake too much and wash off too much entry speed. Better to approach at the right speed then power thru and increase mid corner speed. When I pin it out of the corner 4th doesn't let the back go, but still provides plenty of grunt and acceleration, and the next corner's right there anyway.
Rapid changing up and down thru the gears sounds cool, and a good rider might be able to make up a little bit of time between corners, but I think it would be pretty minimal, and concentration lost in changing gears, controlling rear slide and grabbing handfulls of brake, then changing again, instead of planning the corner might actually slow you down while making it feel faster. A smaller, less powerful bike needs the gears to keep in the power, but the 'busa's torque will just lope along in 4th keeping your riding style smooth and not unsettling the bike, and just maybe . . . making you quicker overall. ???
