Picked up an Obsession on sale because wanted to see what a Hammer heavy asymm looks like. Not to be a shill, but I love this ball. One of the rolliest balls I've ever thrown. This ball is digging and trying to read before it leaves your hand. And when you play with surface, you can dial in this ball to do just about anything. I also love the big mother loving core that blasts through the deck and has one of the noticeably biggest pin action hits in my arsenal. Has one of the most distinctive shapes. And I can't emphasize how rolly this ball is enough. Just toss it at the breakpoint and let the ball do the work. One of the easiest to throw, highest performing balls I've ever experienced.
This ball does require some regular maintenance, as it will lose performance and dull into become weak over time. However, hitting it with a 1500 or 2000 pad when performance noticeably declines along with regular ball maintenance should keep it nice and lively for you.
