I wouldn't sweat it too much. The first gendarme pitch is fairly easy for the grade. It is an excellent pitch, but I don't recall ever climbing anything particularly similar. It is more or less a series of jammable or underclingable roofs separated by excellent rests. The 2nd pitch is typical 5.9 OW, but only hard for a short distance. If you are comfortable on any of the classic 9s around (godzilla, princely, inca roads, etc), I wouldn't expect any trouble at all.
