Wow, what's your definition of "everyday speed riding"???
Your bike's peak power range is likely 10,000-14,000 rpm, shifting close to the 14k point will keep you above 10,000rpm in the next gear for when you're really pushing it (or as I do riding with big-bore riders), but for just cruising around town, anywhere from 5,000-7,000 is probably a good range on a 600 I'd say.
Everybody has their own style. Just don't bog it down, to me that's harder on an engine than running it up a bit...
