Here is what Prodigy has to say about the PA-5:
 
The PA-5 is a silky smooth understable putter that will hit beautiful slow turnover lines and dead straight hyzerflips. It has a narrow feel in the hand for an easy release. That shape also gives it a little more speed that you will quickly notice as you throw it. For putting, the PA-5 fits players who like a straight putter with little movement right or left out of the hand, and it works nicely from long distance.
