In reply to Flinticus:
A cheap screwgate if you can't finish a route. We were climbing outdoors for the first time this week and we were lucky to find a screwgate left by someone on 3rd or 4th bolt. We got stuck on 8th bolt out of 9 so I put a screwgate on 8th bolt. Hence, all quickdraws were collected!
My climbing partner wasn't keen to buy a screwgate with a sling to attach to the lower off point (well, a quickdraw works well too!). However, I purchased it anyway. We ended up using sling both as it's more convenient. You girth hitch the sling (60cm is okay, but I've got 120cm only, so had to double it up) to the belay loop and then clip the screwgate to your rear gear loop. Once you reach lower off point, unclip the screwgate and clip it directly to the lower off ring. Lock the screwgate and you are safe! With a quickdraw scenario, you would have to clip it into the lower off ring, then to yourself and then untie your rope. Hanging on two non-locking carabiners sounds a little bit scary!
Also, a mat for rope is highly recommended.
...and flipflops as well. It's so annoying to change your climbing shoes back to trainers and back. However, some would disagree as catching a fall with flipflops might be more dangerous.
