Hi Chris,
Did this route last september. Can't really help with the topo but I was climbing at a similar grade I think our experiences might be of use. We hauled a small haul bag and the leader hauled whilst the second jummared. Climbing with a seconds rucksack would be difficult imo due to the amount of water you need to carry, and also climbing the chimneys around pitches 13-16. In terms of gear, the obvious jummars, etriers etc but no need for a portaledge or any specialist gear (apart from 2 cam hooks, i'll get on to that...)
Day 1, walk in and climb the first 4 pitches and leave fixed ropes. Possibly 1 or 2 points of aid on the first pitch, multiple points of aid on the 4th pitch (especially at the start). I would say it's worth taking the extra rope to be able to fix the first 4 as the 4th pitch is time consuming and would be a pain to be the first pitch of the long 2nd day. You can always just drop that rope and collect it later if you don't want to haul it up with you. Sleep at the base.
Day 2, Jummar first 4 pitches, free climb the majority up to big sandy (pitch 17). There's one easy bolt ladder (possibly pitch 11) with a pendulum but pretty straightforward stuff. Big sandy has plenty of room (8 ppl approx).
Day 3, the zigzags go at about E1 but for speed we pulled on the odd bit of gear. At the Thank God Ledge make sure you know how to lower out a haul bag (simple but worth practising). After TGL is the mandatory aid pitch. I reckon you might be able to do this with some RP's or possibly offsets but camhooks work really well and aren't very expensive, I'd say it'd be worth you picking 2 up(large and medium, maybe 2 medium). After that it's plain sailing and then a long walk.
There's some decent easy cracks low down in the valley (the cathedral?) which are worth having a quick go of aid on before you get on the wall, day 2 is long and you want to be moving well.
Hope this ramble is of some help!
