RE: U-can-do 46 or 60
Exactly. I would venture to say that, at least in the case of the 60 size UCD3D, it can fly as tame if not more tame than a 60 size stick due to it's very thick airfoil. We have had a few guys go to it as their second plane and first low wing.
If your deciding between the .46 and .60 remember the golden rule. Bigger flies better.
