So I want to build a lightweight upper to go with the lower I built 1.5 years ago. Currently all my barrels are Colt, my favorite being the SOCOM 14.5 upper. So I want barrels of equal or greater quality. Now I want something lighter, easier to carry. So far my choices are DD skinny, Centurion skinny or on the outside, JP makes an ultra light 14.5. It's JP expensive so I'm not sure I really need it? But I will if it's clearly superior. My uses are general protection, 2 gun matches, etc.

Anything else to consider?
