I think your remembering your days out with rose tinted specs.....rabbits being bolted by ferrets in to stop or long nets bounce on a regular ocurance .....
its the fact the rabbit is running full tilt that causes the bounce......night time longnettng your trying to get the rabbits to trot or walk in to the net....rather than run full tilt....rabbits the trot in to a net a far more likely to tangle....
