Looking for little advice or recommendations. Do any of you use a slinger type leash like this one?

Or do most of you prefer something else, like a more traditional slider leash?

Just curious. I like the idea of the slinger and it gets very good reviews on many of the gear sites. I would just prefer to get feedback from the crowd here.
