I have a Widow Spare that I bought to play straight with on our local house shot. Early on, it was money. I was able to play up first arrow, hammer on it (I'm a no-thumber with a Tom Daugherty-like style, just not the talent), and have firm control of the pocket. If I got it in, it fought the oil, but my revs and the core allowed it to find the pocket, and the hitting power was good. If I was a bit wider, it read the friction on the extreme outside and charged back to the hole. Things were great...and then the shot changed.
I don't know if the center deliberately changed something, or if things are just playing differently because of the change of weather with the seasons; nevertheless, I've had a heck of a time using it lately. The outside are so dry that despite being plastic, this ball snaps off the dry hard. I threw one during practice last night, and the ball backended like a reactive and damn near went Brooklyn! Sadly, being polished plastic, moving into more oil really doesn't apply because despite the strong core, there still isn't enough strength there to truly play it in oil. Now, maybe things would be different if I knocked the shine off, but I have a true spare ball (Target Zone) and two urethane balls I can use when moving slightly left. As such, the Widow just hasn't been a good option for a while now.
I mention all of this not to say that it will be a bad option for you. I don't know that. I'm just warning you that if you're encountering the friction you alluded to, you may find the Widow Spare too strong to play straight, but not strong enough to move in unless you do surface adjustements.
