If you use 16 pound equipment look into the visionary Blue/Green Centaur. Bowlerscellar.com was just selling nib 16lbers on ebay for $75.00....they don't list it on their website, but they listed them on ebay which recently ended and they haven't relisted yet...check with them.....Although back when I had the ball it wasn't the right match for me, several Posters here....Namely Charlest and Scotts33 will swear by the ball on lighter drier conditions. One thing I remember well about the ball was that it did hit extremely hard.
