stone,
While I think that the Black Widow is certainly capable of being used on carrydown conditions, I wouldn't recommend it.
In most cases, on carrydown, you want to bring the breakpoint closer to you in order to get the ball rolling heavily as it enters the pocket.
The Black Widow, in general, likes to push down the lane and offer a lot of movement on the backend. That is fine when you have clean backends, but when the oil is pushed down, that late backend move will cause your carry to suffer big time as the ball will still be trying to hook when it enters the pocket.
The only way that I'd try using my Widows on carrydown would be if I still had enough head oil to square up a bit and could then change my hand position to get the ball rolling earlier. Then I'd say you have a viable option.
So, in conclusion, I guess I'm saying that YES, it is possible to use the Black Widow on carrydown, but I wouldn't try to do so unless you're comfortable changing hand positions and manipulating the timing of your breakpoint. If you expect to be able to keep standing left and throwing right, I think you'll be disappointed with the results you see. Just my .02.
Good luck and good bowling to you.
