By dulling up the Jet Black Taboo, it will be smoother off the spot... for me, the JB Taboo was too skid/flippy, then when put surface on it, was a little too smooth for what I wanted... the BWA is what I needed to JB Taboo to be... smooth, yet angular enough to not be over/under - the cover (First Blood solid) does that for this ball.
I like to mess around with surfaces in the beginning to find the right ball motion that I want in my tournament bag... I found the surface on the BWA of 1000 w/ FF polish is perfect for this ball - for what I see in my game... it might be different for other bowlers.
The difference that I saw with the JB Taboo & BWA with the same layout and surface is that the BWA was about 5 boards stronger overall (earlier & smoother down the lane - due to the coverstock).
Hope this helps!
