Thank you for a quality product. I am very happy with my purchase. I can not say my maximum casting distance was changed with the Boca spool bearings. I can say very confidently, the roll,pitch,and normal casts go much farther than before. On the maximum distance cast, you can tell clearly when the spool brakes engage and release and the spool tension takes over. Accuracy is much improved as well because you use much less power to make the cast. I will be ordering more.
