No its not much.
I bought some BABOLAT lead tape. I think it came in an 18 grm +or_
i had bought a Rossignol that was 11.25 oz and wanted to bring it up to my other ROSSI thats 11.75 oz So i added 15grms. Really its not that much length and works well. I have not had much luck placing lead on the head but, like placing it on the handle.
