The steel Fanatic BTU features the Low Differential I-Block core matched with our new low friction BTU coverstock formulation to produce “urethane” ball motion with improved consistency and enhanced hitting power on high friction lane conditions.
The Fanatic BTU can be drilled using the standard drilling techniques developed for symmetric core bowling balls.
