Double-Rib Slim Profile Nymphs
We've all seen what simply changing the color of the bead on your average fly can do here lately.
In that vein I'd thought I'd add another "simple twist" to the mix.

"Sometimes relatively minor changes to age old fly patterns can make all the difference on pressured trout streams. Lately here at chrome head quarters we’ve been concentrating on 2 important factors in nymph construction which are getting a fair amount of attention in competitive fly fishing circles. The first is simply achieving a “slim profile.” Most flies call for layered dressings that produce an end product that is fairly heavy in the mid section. Utilizing Biots is one direction toward insuring a slim bodied nymph – just using thread is another. “Double Ribs” are the second and the sky’s the limit. Start with normal materials like wire and branch off to rubber legs. Play with variegated materials for even more realistic body looks!"
