In reply to thwapy:
In all seriousness, I'd love to have five Beal Opera 8.5mm single ropes in 30, 35, 40, 50 and 60 metre lengths.
Climbing on the skinniest and shortest single rope you can possibly get away with is easily the best way to massively save weight both for climbing and for any approach.
For various reasons, I ended up climbing Eastern Hammer (E3 6a) this Summer on my 40m Mammut 8.7mm single which worked out great and made the walk-in distinctly more pleasurable than normal
I've got various items of specialist lightweight gear, many previously mentioned on this thread, but having actually used them a bit, I probably wouldn't pick them for any remotely hard climbing:
- Metolius UL cams (annoying and fiddly)
- Metolius Alu Nutkey (not that great at removing nuts)
- Edelrid 19G krabs/draws (rather too small to use when boxed)
- WC Superlight Offsets (colour-coding annoyingly mismatched with standard nuts, especially DMM ones)
Finally, as far as cams are concerned, I'm currently on double sets of WC Zeros and original DMM Dragons but if buying again (money no object) I'd probably go for Totems.
