The adjustments are still the same. Or I guess I should say same will get you at least close. As to more or less critical yes and no. Depends on what you are trying to receive but basically the larger the dish the larger the side lobes which can get rough to distinguish from the actual signal itself. Worth every bit of the install though as more surface makes for more signal trapped which makes for a better picture.
