Organ donation versus cryonics

Simultaneously signing up for organ donation and cryonics versus only cryonics. Does having less organs decrease the likelihood of cryonics (including revival) working? Is it a good idea to have only your head frozen anyway, to save on electricity and storage? Do the benefits of organ donation outweigh any costs it could possibly incur, since organ donation is known to work?

Discuss.

I’m an organ donor because signing up was quick and easy. I’m not signing up for cryonics, because I anticipate that my family and close friends will have a harder time overcoming their grief if my body is not actually present at the funeral.
