Judd
Judd is a strong but sensitive short form that can easily stand on its own, the second 'd' giving it a lot more substance, and it would also be a good middle name choice. Two recent actors have given it credence--Judd Nelson and Judd Hirsch, and now it's most noticeably represented by comedy director Judd Apatow.
Judd is a fairly prevalent surname, represented by the family of Naomi, Wynonna and Ashley, and the minimalist artist Donald Judd.
