Could your golf grip size be the hidden factor affecting your consistency, accuracy, and club speed?
In this episode of The Mind Caddie, I sit down with John Mazzanoble, CEO of JumboMax Grips, to explore one of the most overlooked areas of golf performance: grip size.
Most golfers spend hours working on their swing mechanics, yet the grip is the only point of contact between you and the club. So why is grip fitting often ignored?
John explains the science behind grip size, grip weight, and non-tapered grips, and how these factors can influence shot dispersion, clubface control, swing tension, sequencing, and overall consistency.
We also discuss:
• Why Bryson DeChambeau chose JumboMax grips
• The relationship between grip size and shot dispersion
• Whether thicker grips really cause a slice (or if that's a myth)
• How grip weight affects club balance and feel
• The role of counterbalancing in modern golf equipment
• Why most sports use larger, uniform grips while golf remains different
• How grip size can affect club speed and tension levels
• The benefits of non-tapered golf grips
• The importance of proper grip fitting
• How the JumboMax app uses AI to help golfers find the right grip size
If you're searching for more consistency, better ball striking, and improved golf performance, this conversation may challenge everything you thought you knew about golf grips.
