so if you don't remember which finger you used on your previous trip with a MB and you use a different finger with the new MB on current trip would all the past MBs then use the "new" finger or would you have to use what ever finger you used prior? Am i explaining this right?? I was going to bring my old mbs this trip (you have to match your outfit with your mb LOL) but if i have to use different fingers for each band then forget it, I'll get all confused! The reason is now with the new style MB i'm going to use my right hand for the MB (non watch hand) because the new MB are bigger and not comfortable with the watch and MB on one wrist.
