Thanks for the info Bianchi10
My brake calipers (entry level R350) weigh in at 365g. I looked into the Planet X calipers. There's a $40 and 25g difference between the CNC and Forged...I'm guessing that is where price to weight ratio gets bad.
Current upgrades I have in mind (just from perusing the Weight Weenies weight listings):
Deda Black Stick seatpost
Planet-X Ultra Light Forged calipers
Ritchey WCS C260 stem
Easton EC90 drop bars
