Routes are always less fun when they're sandbagged. Makes it hard to appreciate them. This route has, IMHO, 5.6+ or 5.7 moves in the start. Not a 5.4. Note I've done 5.7s and 5.8s on the wall. If this is a 5.4, Jolly Roger (5.5) is a 5.2.
Looking forward to doing it a second time, though, now that I know what it's like. Consider the first half a hard 5.6, and enjoy it!
