Hi. My husband and I are trying to determine which size Le Creuset Oval French Oven is best for our needs. We'd be cooking for 3 people most of the time, but will sometimes be cooking for more. We want something large enough for a whole chicken. My husband is leaning towards the 9.5 quart. I'm trying to decide if that is overkill and if we'd be better off with the 6.75 quart instead. Any advice would be appreciated. Thanks!
