Hexy Fiber is one of the very few shaped multi-filament strings out there. While claiming to increase spin (ball bite), it doesn't do this in the same fashion a textured poly string would. Instead Dunlop has created a string that is one of the softest strings I have ever played with. This string softness, even at high tensions, allows great ball pocketing on the string bed which will, in and of itself, lead to better spin production (as long as you are not hitting 1970's style continental grip forehands).
