+1 on Garth's recommendation to use a road double. Something else to consider is the BB spindle length. Is it longer that needed? I had a nice SKF BB with a long spindle and had over shift issues as well. I switched to a BB with a shorter spindle which helped a lot. Also improved the chain line and reduced the pedal Q factor.
