Looks like Calgary based Fish Tales Fly Shop Cuban spring fishing trips are booked up. These guys are fairly helpful though with equipment and contact info to any who want to organize a DIY fishing day or two in Cuban fishing areas.
I met them in the Toronto airport a few years ago - seemed to know their stuff !!!
They’ve been organizing fishing trips to Cuba and other countries for awhile, should have it figured out by now.
They were on their first tyrip when i met them !!!
Some other good fish forums / reports Googe :::
