Finished with a High Gloss Polish, the Marauder is very clean through the front midlane, revving hard on the backend to create a very strong and continuous motion that drives through the pins on medium to light oil lane conditions. The DV8 Marauder can be drilled using the standard drilling techniques developed for bowling balls with symmetric cores. To reduce oil absorption and remove dirt from the surface of the ball, clean your ball with a cleaner designed for reactive bowling balls. Look. We don't screw around. DV8 bowling balls have been manufactured to the highest standards of workmanship and material. We warrant that they'll be free of defects in materials and workmanship for a period of two years from the date of purchase. We agree to repair or replace the ball you bought if at any time during the warranty period it's found to be defective in material or workmanship.
