I've primarily focused on rotogrip and storm for the past year or so. Bought a few motiv balls to try and now I'm thinking I want to try hammer. I do have a few questions. With the carbon fiber tech and the 3 year warranty has anyone had any issues? I've had several storm balls Crack on me and not old ones. Also hammers slogan is nothing hits like them, is that true? Do they actually hit harder than most or is it just a catch phrase for the brand name. Also what balls would you recommend getting? I was thinking of getting a BWRLS and a viral pearl to start. As they would compliment my current arsenal. Then go from there.
