My diablos are around 8-9 HL with overgrip but some are more headlight.
Thank you very much, I will go with the 12g at the top of the grip. If I'm doing this right, I have 4 strips (each weighing 3g) and apply them vertically down the grip from the top, with one strip on each of the main bevels?
My experience with lead tape is very minimal.
