Wayne,
     I'm not suprised the solution to your Bottom Bracket problem was an OMAS piece fitted backwards. That's because this should give the same chainline as a symetric Campagnolo BB. If you tried a symmetric Campagnolo spindle (e.g. Record/NR Pista, Gran Sport Pista, Athena road , early Chorus road, or whatever) and one of those didn't work properly... now that would surprise me.
     Still, there's obviously nothing wrong with your OMAS setup.
