I had a great time, first with a VERY knowledgable guide, Rob Arita, 914-523-8920, then on my own.
I was successful, but casting challenging, as all fish seemed to be offshore from me, and the trades are East to West -- so over ones right shoulder.
If I used 8 lb tippet in Belize -- here you are talking at least 15lb tippet.
Have a great time!
