No not a necessity. If its more comfortable and you have less tension, than it may benefit you. You may have to play a little more with the larger grips, before you decide fully if its a go for you though. Certainly, it has been said and others who have tried them have reported that you may not turn the ball over as much. For some, it may help to turn it over due to less tension in your hold on the club. Don't change a thing if it works.
