To clarify,I should have said a 'whip'
I think the 15ft whip is longer than I need.
By the time you measure the length of the whip,then almost double it with the length of line,the range is about 28ft-30ft.
The idea is to lift in the fish without collapsing the whip.
I can see the point in not using elastic.I think there is a fitting that fits on the end of the whip that replaces the elastic.
The problem with that is it puts a lot of strain on the top section if the fish is on the large size.
I was fishing at the entrance where the canal widens out into the marina,
I had the whip set up,but was using a rod.A large shoal of young carp came into the marina,so I picked the whip up and dropped it amongst them.I got an instant take,but the carp was about 2.5lbs.
It stretched the elastic out to it's full extent and I had to partly collapse the whip in order to land it.
I think once you get the knack of using a whip they are probably easy to use.
