The Bill Siemantel Signature edition SPRO Phat Flies were designed to take Float and Fly fishing to a new level. Not only designed to catch fish in the harshest conditions, Bill designed these jigs to catch big California trophy bass. Colors painstakingly matched to the most prevalent baitfish in North American waters. Perfectly balanced to sit horizontal under the bobber. Built with the worlds sharpest Gamakatsu hooks. The SPRO Phat Flies are the best on the market, period.
