Go 144 (2008) vs. Go 139 (2007)

Hi there,

Does anyone know what difference is between Go 144 (2008) vs. Go 139 (2007), in termes of planing, (top) speed etc ? The Go 139 (2007) was as we know tested very good in de german Surf, but the shape of the Go in 2008 is quite different. Any experience with the new Go 144 ??

Thanks for reply
Greetings
