Unfortunately there is no "scale" to judge wing loading. Lighter is usually better but there are so many other things that effect the way a plane flies. You could have two identical size and weight planes, if one has a 12% thick airfoil with a sharp leading edge and the other has a 14% with a round leading edge they will be VERY different planes. Some people like to use "cubic loading" and based on that the laser is very good, but it to can not compensate for all the variables.
As far as the Hurricane, the new one is powered with a Brison 3.2 and its very over powered, I think the 2.4 was probably a better match for the airframe but it does fly great, and it will accelerate vertically like it has afterburners.
