You'll become obsessed with the performance of the Brunswick Fanatic BTU!
BTU stands for "Better Than Urethane". Our new BTU coverstock provides that old school urethane reaction shape but with improved hitting power for today's conditions.
The Fanatic BTU shares the I-Block Core shape with the Fanatic but modified to a lower differential to reduce flare potential. This reduction in flare gives the BTU the smooth, consistent and predictable reaction that we love about urethane.
Here's what Brunswick has to say about the Fanatic BTU:
The Fanatic BTU offers smoother ball motion so that you can control the pocket. The Low Differential I-Block core matched with our new low friction BTU coverstock formulation to produces a “urethane” ball motion with improved consistency.
