To quote a legend:

the drilling is done for function and weight reduction. if drilling is slightly off a rider would never be ble to feel it. you ride a bike with your legs, not your eyes. noone has ever won a Tour De France using their eyes. this is not for old men trying to create a museum type bike that they always wanted. this is for a person to need to reduce weight and to be FAST!

This crankset is not for the older man who is trying to recreate something ORIGINAL that he always wanted and say "i finally got it after 4 decades!". this is for the person who is actually riding and getting a good deal on a very good crankset."DONT BE AFRAID TO STEP OUT OF THE BOX!" If you fall down and break your hip it just means your rode to the very end of your life! That is called passion!! and you have Obama care! THE WEIGHT IS VERY CLOSE TO SUPER RECORD 11. I KNOW MANY BABY BOOMERS MAY NOT HAVE NOT HAVE THE PRIVILEGE TO OWN SUPER RECORD 11. BUT THE WEIGHT IS VERY CLOSE. AT ONLY 10% OF THE COST! THIS IS A DEAL! YOUR WHITE HAIRED WIFE WON'T GET ON YOU FOR SPENDING TOO MUCH! EVERYONE IS HAPPY! ask her for permission to bid.
