arusha - my suggestion - you are hiring a boat, let the captain suggest where you go. they know FAR more than the rest of us, and have the best suggestions. they know where the fish are, what time of day, etc. the rest of us are amatuers (even me!)...trust the experts. You dont need to decide until you get here, or even until that day. the weather will make a huge impact on where you go and how long it will take you to get there. trust your guide.
