Thanks goes out to Eric as always in providing a test ball, I've had the Wisdom for over a month, thrown it on old beat up wood surface and new (4 yr old ) Pro Anvil surfaces. The first thing you notice is no matter what the lane surface is or the volume of oil is, the ball hooks, this is not by any means a ball only for older gentleman, it is a ball that will fit any bowlers game !! Billed as a medium oil ball, higher rev players will get more out of it than the straighter players, the Wisdom is just consistent shot after shot. 

The medium rg core (2.54) allows the ball to rev easily off the hand, the polished surface gives it easy length up front, while the medium rg diff .041 has enough recovery to come home on wide targeting issues. The biggest asset  of the Wisdom is the cover stock, the S-65 pearl is strong enough to recover on wide shots, provides enough friction to be strong, but best of all under control, a true control pearl. Rolls great, more hook than advertised, at a very attractive price point.
