Climbing Buddy in North Madagascar??

Heya,

I'm a climber who would be stoked beyond belief to get on rock up in Diego Suarez (Antsiranana) and Nosy Hara. (Look them up and let your palms sweat!) I'll be up there 7-31 of October and am keen as beans! Am planning on doing some diving aswell as walking, but climbing is just..climbing. Has anyone climbed there before?! Should i bring my full trad rack or just a sport set up? Any advice is super welcome :)

Peace,

Hann
