It is mostly nitpicking at the point you are at. Although you could likely get below 10 pounds for around (if not less than) $50.
- Leave extra clothing at home
- Switch to Petzl e+LITE
- Switch to the SAK (Swiss Army Knife) small classic
- Replace the extra long strap and biner with an amsteel dogbone extension instead
Those few things alone would get you almost 2 pounds. You can find both the Petzl e+LITE (around $25) and the SAK Small Classic (about $15) online.
