I did the TW customization tool, and I am told to add 0.9 gram 1/2 inch up from the handle (then 11.1 grams at 11 & 1 o'clock or 28.4 inch spot). That 0.9 gram is virtually nothing. Would it be okay if I just tape a penny under the grip? Should that do the trick? It just seems a pain in the arse to try to guess how little lead tape that would take.
