You'll find several solutions to this exasperating problem. First, use leaders no longer than 7 feet; if the fish are really working, cut it to 5 feet. Also, avoid using poppers that are heavy and therefore difficult to cast. The head of the popper makes all the commotion, so try building poppers from Ethafoam (a very light closed-cell foam) that have a large head but a body that tapers rapidly toward the rear. Also, heavy hooks are tough to cast, so use the more expensive, lighter-wire hooks. Don't wind a lot of hackle around the shank; instead, use a minimum of bucktail or similar material tied so that it extends out the back. This makes a full-bodied fly that will interest the fish. This combination of material, Ethafoam and light hooks will make lots of noise and still cast a long distance. Fish will destroy this popper more quickly than a hard-bodied version, but they're easy enough to make.
