you said that you enjoyed Black Widow, but that you wanted a softer alternative if I remember correctly. Black Widow already is one of the softest polyester strings on the market, so you'll have difficulties finding any poly strings that suit your liking (I don't think you'll find Cyclone comfortable if you found BW uncomfortable…). Therefore, I immediately thought of multifilament strings, particularly ones with similar playing characteristics to Dunlop Black Widow. Hexy Fiber essentially is the multifilament pendant to Black Widow (also shaped). It will play similar to BW, though with less control and more power; however, you can dial that in with tension and it will be much more comfortable. The other strings you mentioned are smooth and the launch angle/string response will be very different with them in comparison to your BW. Also, you should play the multifilament in the mains as the mains greatly determine the stringbed's characteristics, so the multifilament in the mains will be much more comfortable. Furthermore, multi (main)/poly hybrids generally produce more spin than poly (main)/multi hybrids due to less string friction allowing the mains to snap back more and produce spin.
