i haven't read the whole thread, so i apologise if someone has mentioned this before, but i think there should be another menu option (or one that replaces "null") and that should be called "v10". this will being up the old default impedance curve. this will allow users to keep their old presets unchanged if they want and also allow them to have a look at what the old curve was and pick a new curve that's closest. like some of the old features we had access to previously with the II, this option could be removed in a later firmware if the consensus is that it could go.
i think the new firmware should choose a new default, as cliff suggested, but if you don't want to change, then you could simply to a batch update with fractool to set all the presets to "v10"
