This is Haywood. Heidi and I are the ones with the fly shop on Caye Caulker (I'm not a guide, just a fly shop). However, we're in Texas right now having a baby and won't be back until December. All of the guides mentioned above are excellent leads. If you have any more specific questions, feel free to contact me directly at firstname.lastname@example.org
Enjoy your trip!
p.s. Hello to everyone on Caye Caulker!
