Batman: Arkham Knight - Riddler Trophy Time Limit (3496,2540)

This Riddler trophy is located in Bleak Island involves retrieving it within a time-limit from Miagani Island to Bleak Island. I had a go within gliding rather than driving to get there, staying low and using the bat grapple to boost was the best way to go. I screwed up at the end , but I managed to grab it just in time! A precise dive bomb at the end should get it in less time. (Or just use the batmobile. But nothing is more bad ass than gliding across town!) Know a faster method? Definitely suggest it in the comments below!
