Replacing my Ultegra 6500 BB

Can anyone help me with replacing it with the lightest BB and Crank setup possible?

It is a single. I only run one 39T chain ring and a 14T in back.

I currently have the bike down to 14.7lbs

the current bottom bracket is ultegra 6500 68x109.5 Octalink V1.
my current cranks are dura ace 7700 175mm 130bcd

I am looking for the lightest conversion possible for both BB and cranks. I am hoping I can find a titanium or better yet a carbon spindle option. I have looked everywhere and am feeling a little mottled at this point.

Thank you Weight Weenies!
