#4 - FEEL
A golf ball's feel is influenced by its construction. Some balls feel soft off the clubface, others feel firm or hard.
Balls with a solid rubber core often feel hard and tend to primarily be two-piece balls. These will typically be more durable and generate better distance.
Balls with a soft rubber core and soft urethane cover will feel soft and tend to be three, four or five-piece balls. These will typically not be as durable but they will provide much better control and spin around the greens.
Low-compression balls will generally have a soft feel, but not all soft balls are low compression. Most high-compression balls are made of multiple layers so if the outer cover is relatively soft, the ball can still present a soft feel to the player.
