I have just purchased a BD (15lb, 3 & 3/8'oz top weight, pin 3 & 3/4's) and would be interested to hear of other owner's experiences of different layout's. My specs are ave speed 17mph  / mid track  / medium to high revs & I prefer to play down and in on the 10th if the conditions permit. Tend to play on freshly dressed lanes in my league.  Currently using a stacked WCCP as my main strike ball with the pin about 2.5 ins above the ring finger but was using a stacked Big Bang (still have but it's ageing and needs a rest) until recently where the pin was just above the ring finger. I have a spinner etc and tend to experiment with surface tunings (probably too much for my own good).  

I'm after a strong arc on medium oil - maybe a label drilling would be best?  Welcome your thoughts ........
