I mostly use status quo. I DM a tweeked pre-Wars Greyhawk setting and generally consider the old 'name' level (aka 9th; but IMC its really 7th-11th) to be about the time when the PCs are on the cusp of high level and low level play. My group is currently at that part of advancement and they're reputations are probably bigger than they are. They've taken on a few status quo adventures that they probably shouldn't have (my version of Castle Greyhawk -- survived, kudos to them), or else should have been more careful in the face of great danger. They got through it though, and have made powerful enemies above their CR fear them and overestimate their abilities. (Its funny when a fabulously rich 13th level enchanter with an army of enchanted monsters fears a group of adventurers when they're initially 7th-8th level.)
The players, despite my warnings, are surprised that I've 'thrown them against' a much more powerful foe (whom they sought out due to their evil reputation). They've persevered though, despite some PC deaths, and they're on they're way to high level play..
