I have the 09 84l twin....i am by no means a great wave sailor but find that with this board it makes snappy turns without too much effort and holds the rail well on more drawn out turns...planes pretty early; I am 93kgs and had a 86l freewave before this and find the twin easier to sail and get going,also pretty forgiving if you catch a rail;just seems to slide out and bit and then comes back into line........dont want to get into an argument about comparing singles,twins,thrusters and quads but i think that the twin for me just makes it easier to be a better wave sailor...
