Problem with guitar slinging

[XLayaR]

Hey guys...You know how some guitars, cos of their design and all, the neck will tend to sink down when you sling it around you cos the weight's not even and all?

is there anything that helps to keep it up? i.e Some kinda special strap....

leather straps help if i'm not wrong..
