I am currently using a grip 4 3/8 and I would not like to increase the grip size much. It would be desirable however, for the leather to be slightly thicker then the 'White Hydrosorb grip' that comes originally with my MG Prestige. Can anyone provide info on thickness of Babolat and Vantage Leather??. Much appreciated. Forgot to mention I will be using a tournagrip ontop.
