This very much depends on what you are wanting to achieve by changing your grip. For example, if you wish to continue using a pistol / pencil size grip then choosing a Snug Daddy 24 or 27 will help with your grip alignment and consistency of stroke. If your primary goal is to confidence with shorter length putts, then opt for the Snug Daddy 24 however if your goal to gain greater control over long distance putts then the slightly wider Snug Daddy 27 would be a great option.
