In reply to RichyBOYY:
Compared to grit I think the most important thing is the rock quality. Check that whatever you're placing is in solid rock. Nuts are king, I take a set plus offsets plus brassies on most stuff on limestone. Sometimes with extras of 2-6. Be inventive with nut placements and seat/extend them well.
Cams are to be treated with suspicion, sometimes they'll be the only option but I'll always go for nuts/hexes/tricams before SLCDs unless it's a really good pocket or similar.
Also take a few thin sling for threads. Friend of mine has a few of the edelrid aramid slings, these seems like they'd be great for those one handed fiddly threads.
