This Version of S-force has been developed for trout fishing with the special style of "bombarda". Those special floats typically used in Italy, but now spreading across Europe. The Particular structure fives a very low memory to the line, but offers a great softness. It is completely waterproof and keeps all the technical prerogatives in extreme cold waters. The color is a new pastel violet, immediately visible out of the water, but almost invisible in depth.
