Steve,
Don't be so quick to discount the performance of the Husky as compared to the Cub. You are absolutely correct, weight does equal performance, but power and aerodynamics are also part of that equation, and the Husky has lots of thrust (the Top Cub has the HP, but can't deliver the thrust THE SAME as a constant speed prop can) and don't forget that the Husky has a different airfoil, and those magnificent flaps.
As to takeoff performance, I doubt there are many Cubs that can compare with the Husky's takeoff performance, particularly in challenging situations, such as floats and skis.
Landings, on the other hand, really do require much more skill on the part of the Husky pilot to keep them short. It can be done, but it takes a good bit of skill, and a lot of practice to stay current at short stuff on wheels in the Husky.
As I noted in my earlier post, they both have their favorable attributes.
If it were to be a ski/float debate, there's no question in my mind that the Husky would beat most Cubs, with comparably skilled pilots.
On wheels, the edge would likely go to the Cub, because of its landing characteristics.
Weight is certainly important, but it isn't everything. Take a single engine Otter, you would be astounded at the takeoff performance of the thing. It'll whip any 185, 180, or dang near whatever off the ground. Keep it light, and it'll compete with the Cubs and Huskys.
I also have to give Cub Crafters credit for producing some pretty light (it's all relative) Tob Cubs. I think they've done a great job of weight management. They are producing "dresser" Cubs which weigh less than 1200 pounds, and some less than 1100, which isn't bad in the real world.
The advantages the Husky has are the wing, particularly the flaps, and the constant speed prop. Those help in some regimes, but not all.
As you noted, though, the nut attached to the stick is what makes it all function. With a loose one of those, they're all just bags of hardware.
