From what I had heard, the Tsunami is supposed to have a higher hook potential than the h2o. But at the trade show I went to, it seemed to me like the Tsunami merely had more backend, but didn't cover more boards. Actually I was able to play a little straighter up the lanes (even after they had been bowled on for 6 hours) than with the h2o. This kind of reminds me of how the smokin inferno was labeled to be a little stronger than the absolute, but it longer with more backend.
