I can't help but say that this is one of the scariest threads I've ever seen! Ryan starts the thread by saying that his First Blood is coming up a little short on oilier lane conditions. Next, just about everyone and his brother jumps in saying buy this or buy that because it works for me, or it works for my best friend, or it works for my brother Fred.
Every bowler is an individual with a unique combination of speed, rev rate, axis tilt, axis rotation, and PAP. What works for them may not, probably will not, work for you. Look at the facts and the numbers.
Consider that the First Blood has an rg (radius of gyration of 2.48), a differential of 0.056, a hybrid cover material, and a 1500 abralon surface with Powerhouse Factory Finish (polish). The Black Widow Assassin has an rg of 2.50 (goes longer than the First Blood), a differential of 0.058 (very slightly stronger than the First Blood (meaningless unless you have a rev rate of 450 rpm or higher), a solid cover material, and a surface finish of 1000 abralon with Powerhouse Factory Finish polish. So, the First Blood has a core that is designed to roll earlier than the Black Widow, a differential that is so close as to be totally insignificant, a cover material that will read the friction in the oil slightly more, and the friction in the dry slightly less, and a cover finish that will go slightly longer, if both are polished the same, which they probably are not considering that the First Blood was marketed as a ball for medium oil, and the Black Widow as a ball for heavy oil.
Before you go out and make another $200 donation, change the surface of the First Blood to 2000 abralon (500 to 2000) without polish and go from there. I really don't think you need a new ball, just a new surface.
