I've been trimming weight and one thing on my list to trim is my water system. What is the best and lightest system?

So far I'm using a Camelbak and one small Gatorade bottle. I like being able to drink out of a tube while hiking to free up my hands. It also makes filling easier if I go to a gravity system. The Gatorade bottle is great for around camp to drink out of and to make tea. I guess I could drink out of my pot though because I FBC. I'll have to debate that 1.5 oz. savings.

I'm looking for the lightest 3L bladder and tubing. So far I've found the Platypus to be the lightest. Any recommendations?
