Climbing in Madagascar, sport or trad rack?! Best spots/ guides etc?

over 5 years ago about Madagascar

Over 3 weeks in October, with an expedition all through Sept, but leaving them in Tana and heading off on my own. Practicality of bringing rack or just bare minimum gear? Any info is helpful :)
Also, am thinking of going scuba and surfing aswell, any recommendations where there is climbing around aswell?
