In reply to lwhite89:
I take a 10m length of static for setting up top rope. Some people say take 5m, but it's better to have a bit more as some routes are bolted a little bit back from the edge, or in some cases you use a tree or stump.
On most routes though you'lll get by with your 2 slings.
Rope protector or bit of carpet is a must. If often forget these and end up using my car mats.
