The GAMMERA 50 HW is perfectly balanced and designed to be worked steadily through strong currents vibrating constantly to remain attractive and provocative. This heavy weight version (HW) has a straighter body profile and a low center of gravity to maximize its stability in really fast flows. The extra weight will also help you fish deeper river sections when trout are posted deep. The large lip has been carefully angled to get the balance between stability in fast flows and lively darting when twitched just right. If you fish on bigger, faster rivers this is the lure for you!
