John Fehnel's signature pattern- the Dahlberg Diver. The "Bad Ass Frog" is just what the name says. Bad Ass. This bug chugged in the shallows, in the salad, or downed trees is a munch wagon for Mr. Lunker Smallmouth or Big Ass mouth Largemouth. WARNING: If you have a heart condition do not use this fly, you will want a recliner after an evening of chuggin this bug in late evenings.
