Pin under bridge MB on or a little pass VAL. I almost want to say I don’t care what layout goes on the Effect Tour it will work. I am a fan up, down, left, right, sideways, you get it. Box surface it is certainly early and might not be what you want to see or if you like a little surface on your bowling balls then keep it just like that as long as you can. The Hammer Effect Tour loves whatever you love. I almost want to say whatever surface you decide use that too. I truly think this is a use on any lane condition ball depending on the layout, rev rate all that jazz. However, let’s be honest bowlers know what they like to bowl on, their style doesn’t change much so if you are a fan of a ball that gets better over time and you can play almost anywhere on the lane then The Hammer Effect Tour is a solid choice for your arsenal.
