Working the thin-ish fingers on the ultra short, but ultra fun Dinkum crack. Another good piece to build your trad leading skills for finger cracks. There are 1-2 moves on relatively insecure finger jams between bomber finger locks, depending on how tall you are. There are some sneaky feet to make the crux easier, but it is a nice variation to stick to the crack alone. The crux protects really well with small/medium nuts and/or aliens. :D
