Yep, but you see, Ola, this is getting much closer to marketing and not substance. To get a 10-15% weight difference you have to build the board differently, not just change from glass to carbon, and then all our discussions are moot ... we are comparing boards that are different NOT because of such a simple thing as carbon vs glass layers ..
Just for reference: If a board of the size of my Acid 74 2007 switched 4 layers (sandwich total) of 6.0z S-glass to 4.5oz Carbon the weight gain would be about 150-180 grams. However you probably would not want to go for such a light carbon to laminate the bottom of the board ... so there is goes 1/4 to 1/2 of your weight gain ...
