Well, I guess it depends on your definition of "little" radiation. In my 
case, I have measured greater current in one leg of the ladder line than 
the other. This does not surprise me in that the antenna itself (132 
foot dipole at 25 feet above ground) is anything but physically 
balanced. The dipole is not in a straight line (bent at about 70 
degrees), half of the antenna is over grass, the other half passes over 
the house, different halves are closer or further from trees, etc, etc 
all due to the lay of the land and available mounting points (trees) -- 
so, anything but "balanced". Unless you are very fortunate or have your 
antenna in hypothetical free space, unequal currents i.e. feed line 
radiation, is virtually unavoidable.
