1st, call the lodge/guide. 2nd, although I only fished Andros 3x, I did not encounter much turtle grass, with that said, have some weed guard flys.
Gotchas and various different take-offs of this famous fly should do the trick.
If you can, have a 2nd rod ready with a crab pattern. Check with the lodge as to size of eyes......deep water......or in other words.....small, med, or large eyes.
Any reputable shop should be helpful once you have this info. Recommend you use one of this sites sponsers.
