Hello IvanSounds like a good research prjeoct! My feeling is that this zip line will benefit the local Tagabenit community tremendously. Tourism in Palawan in general is growing at a tremendous rate especially around Sabang.Try getting a hold of a representative of the Tagabenit Guide association better yet you should pay the zip line a visit, once it becomes operational, and interview the locals to get their take on the prjeoct!Tagabenitt, Puerto Princessa City, Palawan 5300Contact personMarivel Orcajada 0910 628 7980dp
