In reply to Ramblin dave:
On the Westgrat on the Salbit (36 pitches) a few weeks ago we walked in from the road (normally you go from hut/bivi but we couldn't due to an earlier partner misdemeanour).

This seemed to work ok (back to the car the same evening):
Ultra Light fell shoes carried on harness of each person
2 sacs to carry kit up in, one lighter sac with no back panel (crux 35l)
Fold the light sac into the one with a back panel (north face 35l shadow)
2 60m 8mm ish ropes (depending on route would be happy with one, but there's at least one big ab on this)
Take a rack as big as you need to climb quickly, confidently and safely. Don't over strip the rack, better confident in your rack than runout, nervous and slow.
Block pitch leading of about 6 or 7 pitches
Second carries the sac
Headtorch each (walked in, and out in the dark)
Nuts and raisins in your pockets to eat at every belay
I think I had 400g of nuts and raisins, two salami sausages, a couple of energy bars and a small pack of sweets
Heat sheets or similar bivvy bag each for emergency
One light down or synthetic jacket each with hoods
Lightweight thermals
2 litres of water each, top up at every opportunity but no water available on route until descent.
A good few metres of tat
Some ultra-emergency food that'll make you feel good when you don't (beef jerky for me)
Knife, very small first aid kit with painkillers, finger tape
Disposable Handwarmer for your chalk bag if it gets cold
Phone with topo on it
Suncream/sunglasses
The sac was quite a pain on this for the second but it is what it is! Gets lighter as you run out of water!
A bivvy wouldn't have been fun, but we'd have survived.
Tactics obviously always depend on the route and conditions, and style you want to climb in. Sometimes I might haul, even for a day route of a few pitches.
