Thad: Yes, but I'd lose the game if it's a game from the next round of a tournament that starts 4 days before I return from vacation, wouldn't I? While I can control my own pace to a certain extend, I cannot control the pace of others. Which makes a Fischer clock too dangerous for my liking.
AbigailII: 30/2/30 would give you what you want, but then I'd be stuck in a tournament that could take quite a while. I don't think there's a common ground. The suggestion for more than one tournament with different time settings is probably the best solution.
