The new BTU Pearl coverstock is Brunswick’s newest innovation in our performance enhancing coverstock technology. The new “Better Than Urethane” coverstock offers an old-school Pearl urethane ball motion with improved consistency. Combined with our I – Block low differential symmetrical core, the Fanatic BTU Pearl offers even more length along with a smoother ball motion so that you can control the pocket with enhanced hitting power on high friction lane conditions.
The Fanatic BTU Pearl can be drilled using the standard drilling techniques developed for symmetric core bowling balls.
At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
