Can't go wrong with......
Hi Ray,
I don't think that you can go wrong with an assortment of Deceivers and Clousers in different sizes and colors. Throw in a couple of surface poppers and you will have an assortment that will warm the heart of any bassman. Don't forget to tie them on stainless steel hooks or the saltwater will make mincemeat of your tying efforts. If your still in doubt as what to tie, check the saltwater section of the Orvis web site for sizes, colors and recipes. Good luck! Given the price of saltwater flies, you should be putting a big smile on your nephew's face. 8T :)
