So a brief update.......
I made it to an ultralight weight with the addition of my new DCF tarp and swapping out my filter for a Katadyn BeFree.
My base pack weight now is 4.5kg including everything I need for multi day or extended backpacking trips.
I’m not sure I am happy with the outcome as I have had to make a few gear sacrifices that I did not really want to make.
The next step will be to do a practice trip with it and I will provide a trip report and let people interested know what worked and what didn’t.
Thank you for everyone’s input and advice, it was encouraging and helpful.
