Totally disagree . Both the Aero and the Zero are just slightly better Lasers with slightly less vices , nothing more.Total nonsense. The Zero and Aero are fundamentally different boats from the Laser. You will never be able to make a Laser the same as either of them by allowing such minor updates as better traveler blocks or more purchases in the vang.
In fact if the laser had sorted out it’s mainsheet ( at a small cost) and adopted, as a option, the Australian carbon fibre larger rigs ( at a large cost ) that were trialled a few years ago there would not have been the Aero and the Zero at all. As there would have been NO gap in the market to sell them into .
