I used my No Mercy for the second time last night and had a 646 series. Not great but not bad for a 194 average bowler either. The oil was heavier than the previous week, meaning I could use the ball all three games. Basically I was able to stand at about 32 to 34 all night, throwing out over 15 to about 10 to 8 and the ball was coming back and hitting the pocket just fine, as long as I hit my mark. I could have easily had a 700 series but I missed three 10 pins during the night. In games two and three, the ball hit and carried great. In the first game, it was just one of those games where I needed to make a quarter board adjustment and just didn't realize it soon enough. As a result I was getting tapped the entire game...six times. Add in a couple of shots where I was wild outside and a couple wild inside, during the night, and.....I conclude that, expect for operator error, the No Mercy did as well as any bowling ball could. And it certainly carries on light hits. I wouldn't call the No Mercy a really heavy oil ball....but it can certainly handle medium, medium heavy, even a heavy on the light side, conditions quite well. I'm impressed and continue to be impressed, with the No Mercy, and with Hammer in general at the moment.
