I can use the BW on medium conditions playing up the boards, but I have other stuff that works better better for this. The best look I have gotten with the Widow is OOB on a drier condition. I have been bowling for 27 years and have purchased god knows how many balls. I know what drier lane equipment is, and as advertised this ball "should" not be one, but for me it is. My T-Road Pearl with a weaker drill moves more than this thing and my Blue Pearl Hammer gets the same length (6" pin) with a bigger back end. This is just one of those balls that doesnt match up real well with my game.
One guy on my team who is a top level bowler, has the same read with his, when they break down then he pulls it out. Another guy on the same team (hammer staffer)can use his (3 of them) on various patterns. Everyone has their own style and reads can vary from person to person.
Anyway, to the OP, you asked for opinions from people who have both balls , so there is my opinion. Sorry this got off topic about my so called incorrect read of a ball. Maybe I need glasses, oh wait, I already wear them.
