Is it better for one to get married before Shiva Assar Betamuz and then have some of the Sheva Brachot during the Three Weeks, or better wait until after Tisha Beav and do the wedding then?

Nitei Gavriel (Bein Hametzarim 1: 1) quotes a few opinions that one should avoid on the onset celebrating a nuptials when some of the Sheva Brachos will be during the Three Weeks. Horav Shlomo Miller’s shlit’a opinion is that it is better to do the Mitzva as soon as possible and not to delay it. One may add that weddings performed on the first half of the lunar month are more propitious in our traditions, than the ones done at the second half of the month.
