CDC Hopper 

A CDC Hopper offers a wealth of versatility - it can be - a nymph emerger, dry fly or terrestrial; whichever way you want to fish it, the trick is to move the fly slowly when beginning to recast. So instead of ripping the flies off the water as too many anglers do, incorporate a slow and steady lift before applying the power into the back cast. This drags the flies across the surface, producing that lovely wake that active fish find so inviting.
