Hi mate,
That sounds like a trip and a half.
The big question is weight or comfort?
For me weight wins every time, the less you carry the faster and further you can go.
The quicker you can walk, (turn a 3 day walk into a 2 day) the less food you need to carry.
You can get 2 days of good settled weather but in my experience 3 days is pushing your luck.
I've just got back into backpacking after some time, only to find that all my kit that was
light weight 10 years ago is know mega heavy.
I had a 4 day wild camping trip in the Peak district last month and my pack was over 12kg!
But I swaped my tent, stove and water proofs and therm a rest, rucksack and head torch.
And know my sack with 4 days food is know 7.5 kg.
I found that my old kit on its own was not that heavy, but buy swapping my stove I've
saved 250 gr. And my tent 1 kg.
Good luck mate and I hope this help's.
Oh PS,
I sold all my old kit to buy the lighter weight kit, so it only cost me £50 to swap nearly all my kit!
Cheers Mac
