Just changed my setting on my TS3 driver from A1 to C3. Works really well. I have experimented with the driver settings several times previously. The question is this just to save time. Should the Surefit setting follow the driver setting through the fairway metals and even the hybrid? I currently have a nice shape (slight draw with the fairways and hybrid) with the settings for all three (3 metal, 5 metal, & 21 degree hybrid). Should I try the C3 just to see what happens or is there no relationship? The A1 setting on the driver gave me a slight fall of fade unless I really worked hard to keep it straight. Thanks.
