I bowl on patterns that dry up really front to back, backends are fast, and second shift which is totally dry majority of the time. My bag consists of Medium to "weak" pearls. The Rave 4" pin (snake oil), Turbo/R 4.25" pin (OOB), and Tropical breeze 5 1/8" pin (3k).
At first I thought having a weak ball like the breeze with its long pin to pap layout was a mistake, it turned out to be my best ball for second shift. I had owned two other breezes (s/p) with flaring layouts which were my one two combo for THS where I used to bowl.
I did try the blue hammer and it worked on bone dry lanes with light 4k. With so so results at this house. But it was my "HSK" at another league at another house.
