Between Black Widow and Cyclone (I’ve never tried BH), Black Widow is much softer and comfortable that Cyclone. Conversely, the latter has a harsher and unpleasant feel that I didn’t like the least, although the control was excellent. Black Widow is more tolerant and it can be strung at 25 kgf without any fear, or even 26. Below that, it feels a bit vague and the ball tends to fly out without you anticipating that from the impact. If you are a hard hitter and a good level player, you might prefer Cyclone, but string it lower, 23 or 24 max.
These are my impressions from using both on two identical Pure Drives, and BW itself also on several other frames more, some heavier, some lighter.
There, I hope this helps.
