Al Ritt's new book "25 Best Most Versatile Flies" (Stonefly Press $39.95) is smartly constructed and detailed on that exact premise, and as such, it may well be one of the most valuable fly-tying books any angler--from beginner to expert--can own. Ritt dials in on 25 patterns, and then tells you how they were conceived, how they can be used, and he delivers precise, easy-to-follow, step-by-step instructions (with clear photos) of how to tie them. The book is put together beautifully in a handy bench reference format. It also includes some basic tricks of the trade, like how to apply dubbing, standing hackles, and spinning hair. The bottom line is that once you master these 25 patterns, you can fish many situations for many species--from trout, to bonefish, to carp and bass--and save yourself a ton of money in the process.
