Retro cores and strong reactive coverstocks define the new Avalanche™ series from Brunswick. Using proven core technology from the Teal Rhino Pro and some of Brunswick's most well known coverstocks, the Avalanche™ delivers unprecedented value to the bowling customer. All Avalanche™ balls use the acclaimed Teal Rhino Pro® light bulbcore. The Teal Rhino Pro light bulb core and its Danger Zone modification have been at the heart of two of the most successful balls of all time. The Avalanche™ BlackElectric Green Pearl uses Powrkoil 18™ Reactive. Designed for more length than the Avalanche™ Solid. The Avalanche™ BlackElectric Green Pearl is designed for lighter amounts of oil and a more "down the boards" line to the pocket. With its High Gloss Polish surface the Avalanche™ BlackElectric Green Pearl will matchup well on dry to medium lane conditions Shiny surface finishes sometimes cause the ball to go too long before breaking. Dull the surface with progressively rougher abrasives to increase hooking action. The Avalanche™ is at its maximum length surface preparation. You will need to use a less aggressive ball, such as Brunswick's Power Groove Dry to create more length. The Avalanche™ BlackElectric Green Pearlcan be drilled using the standard drilling techniques developed for symmetric bowling balls.
