The Force reels have, since the introduction in 1997, pursued what is the Holy Grail of fly reel performance: delivering the highest possible ratio of retrieve rate to reel weight. To this end, while other super arbor reels add weight in order to gain speed, Force reels maintain their featherweight specification by being pure muscle and bone. Force SL II has an integrated foot, frame and drag cassette. The integration of the cassette to the frame and foot creates more strength and durability in the reel overall and less weight with fewer added parts.
