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...
"Keep yer feet on the pegs and your right hand cranked."
When I can restrain myself from speeding I always try to get into 5th gear ASAP. For casual cruising I shift out every 5k but when racing I shift out at 11k - 12k since the powerband starts to drop after that.
Best rule I can think of is that when you break in a bike you shouldn't go over 6k for the first 1,000 miles.... So for casual riding just stick with that and you should be able to do 60 in 5th gear without going over 6k... its comes out to be something like 12mph per gear except for 1st. This also depends on the year as well and the CC's of the machine.
