I was actually thinking between these two when looking for a urethane....the vibe core sold me and I'm glad I did go with the blue hammer. when I compared ball averages between the 2 of 3 balls I use for leagues, the blue hammer with 20 games is 221 followed by the breeze at 216. (the third is new to the bag, the lt-48 had to be put away, iffy iffy ball for me)
And on longer pattern houses, I don't bring my spare ball. The blue hammer does the job well for spares. Also, even after so much uses over the last two years, the blue hammer still look real good.
