Quick question for a customization noob: I have two Aero Storm Cortex 2008s that I'd like to bring up to something in between the original Aero Storm (2007) (321g) and Aero Storm Tour Cortex (2008) (328g) weight and standard. What would be the best way to go about customizing these? Lead tape and which position? All are 1/2 grip size with Tournagrip XL. Thanks!
