Hi Dave, That's a pretty good list.
I can't see any waterproof troos in your list though.
You've spent good money on a few of the big things, but could save weight by simply leaving some things behind. As it's a summer list, do you need long-johns and gloves? A merino base-layer top won't stink, and you could leave the spare base layer behind. Leave the rain cap behind if your w/proof jacket has one. The waterproof jacket weight could be halved.
The kitchen set up is quite heavy. One pot (such as a MSR Titan or similar) for cooking, eating and drinking from would save quite a bit.
Do you need over 800g for tools and personal care? A wee knife, small piece of soap and toothbrush could be enough. A simple Platy would save a good bit of weight as well.
The 'sack weight could be halved for the light load you're carrying. Various lighter sacks from ULA, MLD etc.:)
