In term of weight I do not recall the weight of the litepro+bb but it was maybe 20 grams less than the campagnolo+bb. See below the picture of the weight of the campagnolo cranks with the bearings: 480 grams. if you add the bottom brackets cup it is plus 40 or 50 grams = 530 grams in total.
Honestly those additional 20 grams or so worth so much, much stiffer and enjoyable to cycle:
