Good comments above! 
I'll add that I like to use a neck weight and a weight belt. It improves my trim (and streamlining) to have some weight up on the neck. I usually carry 4 to 6 pounds on the neck and the remaining on the belt. This gives the option to to drop weight in two stages instead of an all or nothing option.
