In reply to MischaHY:
some of my favourite shorter routes:
arabe dément 6a+ ( short, easy access.. good start); massacre à la tronconneuse 6b+ (superb); rêve de fer 6b+; heavy metal ( old school but retrobolted ) , belle fille sûre 6b+ ; tanti auguri 6c only about 15-20m but well worth doing ; first 2 pitches of dérobé, than rasoir 6a (afternoon shade ) , barbapoupon 6b+ , saut d'homme 6a , first 2 pitches of surveiller et punir followed by frimes et châtiments 6c
longer routes: demande 6a the absolute classic, ula 6b as demande but harder and only the belays equipped, so take enough gear; pichenibule 6c/A0 the short boltladder is very easy to aid but the position, traversing above the overhanging wall is unique. the pitches below the terrace are not that easy, best abseil down ticket danger + 1 rappel from terrace.
for a change: on the Malines cliff: either babouchemolle (6b+) or Chan-The an old school 6a where a couple of cams (med/large) are useful.
Eycharme: crise de gouttes 6b+ excellent, many 'gouttes d'eau' and morning shade
