Penta TP is the first tour ball with five solid layers—cover, outer mantle, middle mantle, inner mantle and core—engineered to optimize performance in five key shot categories: driver, long irons, middle irons, short irons and wedges. Sergio García, Retief Goosen, Dustin Johnson, Pat Perez and Jason Day, among others, are playing the ball.

You might recall that the so-called "distance" balls of bygone days sacrificed spin, feel and overall short-game performance, while softer-spin balls flew shorter. Today's multilayer-construction balls push the design envelope to limit performance tradeoffs. Yet concessions still exist to a much lesser degree. All of which brings us to the TaylorMade Penta TP. Company officials boldly suggest that it can be all things to all players. "Each layer contributes to different shots," says Dean Snell, TaylorMade's Senior Director of Golf Ball Research. "We couldn't achieve this performance with a four-piece ball."
According to Snell, the Penta TP provides soft feel off the putter; high-spin rates off the 9-iron and wedges; lower flight, lower spin and better overall control (no balloon shots) with the 6- to 8-irons; optimum launch off the 3- to 5-irons; and max distance with the driver. In addition, the Penta's design (each layer gets progressively "faster" from core through outermost mantle) should optimize driving distance for a variety of swing speeds.
