Do new or fresh grips affect swing performance?
A fresh grip will give you the best possible performance of that grip. A clean grip allows more contact with the surface area and pattern of the grip; the two components of the grip that provide tackiness and traction. With a grip that is worn or dirty, the performance characteristics of the grip are being masked. With a fresh grip, your potential to play better is increased. From there, it is up to the golfer to practice, take lessons from a PGA professional and work hard to maximize that golfer’s scoring potential.
