For an OI-connected selector, you definitely want the maximum resistance to be just under 100k, and the minimum resistance should probably be at least 2k to keep from overloading the +5 source. That's why I suggested 15k for six positions. 9.1k will be fine for 11 steps, but I think it's a little too high for comfort if you want 12.
The total series value of an RC-connected "stepped potentiometer" is not that critical, but 100k is still a good target.
