As you already said it has anti tangle properties, it works over nearly all types of bottom and can be cast out when an angler is not sure of the lake bed or whats in front of him or her. It gives confidence and it works.
I travel to a lot of venues for 36 and 48 hr sessions and once I have set up my unhooking mat and landing net a bright pop up goes out on a chod rig while I use my other rod to have a quick look around with a lead and float. Its all about optomising the maximum time available. Depending on what I find I will alter my rigs and baiting stratergy to suit.
