I have used many leashes over the years for my dogs and by far the front range is my new favorite. Besides being so comfortable to hold (especially since I hold three at a time) they are so strong and durable. The locking clip is a huge relief for my husky as regular clips have popped off or broken on him numerous times and the front range has never unlocked.
My border collie puppy plays tug with his leash daily and the front range leash still doesn't have any rips from him having his fun.
The traffic loop is such a nice feature for being able to easily hold my three dogs closer while we are crossing roads or passing other dogs in the trails.
