I spent Febuary in Belize and thought it was fantastic. The people are very friendly and the fishing was superb. I thought the Permit fishing was the best flyfishing i have ever done. Easiest to spot when tailing but they are super spooky. They sure test you for accuracy in your casts.
It was difficult in the beginning to spot the bones but got easier as time passed. They are much more forgiving than the Permit but will both rip line
off your reel fast. You are in for a treat and the reviews shine where you are headed. I took a 6 wt a couple of 8's and a 10 wt. overlining one 8 to a nine, sal****er lines are a must. The water temps run 78 to 84 F. I would suggest carrying your reels and rods on the plane. I left the lines on the reels and got questioned by security in the Dallas airport as they went through my stuff. Gord from Westwinds gave me a letter from the TSA stating it was okay and after they read it they were satisfied. It is the guys discretion ultimately who checks your bags as to whats O.K.
I use this fishpond rod/reel case as a carry on a it works well.
