One note though: if you decide to free the last pitch, you may want to fix a rope to the anchors at the top of the second pitch. Or you can make sure you have some swinging momentum to bounce into the "cave" at the top of the second pitch. I did neither and ended up hanging in space. Fortunately, the ropes were able to reach a ledge where I built an anchor and my partner was able to get to the anchors after me.
