I have used Head HydroSorb Comfort (2.10 mm thickness) and Prince ResiSoft (2.20 mm thickness) to build up my grip size 4 racquets to play more like my preferred grip size 5 racquets. You will be going from a very thin Babolat Skin Feel base grip to a more cushioned thicker replacement grip, so you may have to get used to the new feel. But I can still find the bevels easily with those thicker replacement grips. I do highly recommend using the thicker replacement grip versus building up with a heat shrink sleeve because for me the increased weight of the sleeve altered the weight and balance of the racquet too much when I tried it. The heat shrink sleeves are heavy.
