I am a dedicated Hammer user and have had 3 Original Black Widows. I just replaced the 3rd one with a Black Widow Nasty and in just 2 weeks have absolutely fallen in love with it. I throw about 17-18mph and am a tweener myself. I had it drilled with the most aggressive layout and I still get pretty good lenght with it and a devistating backend. You will need some oil to get the length however. If you typically bowl on dry lanes you won't want the aggressive layout. Anyways my first three series with this ball were 257, 258, 241= 756/ 300, 245, 290=845/ and 239, 300, 231= 770.
The Black Widow was my favorite ball of alltime, but the Nasty is quickly taking over that title for me.
