Leerburg Dog Training | Long Lines
This is where I got my double handled leash for Monty. 6 ft, with a short traffic handle built in. Crazy good quality. Got my long line at tisol, but think I'd rather have one of these. 30 foot long line=60 ft of 60+lb dog to gain momentum in a worst case scenario if your dog has a high prey drive or something like that, so I'd spend the money for quality.
