  Obviously, normal precautions about bending radius should be observed. 
It is NOT necessary for these chokes to have a tight bend radius to be 
effective.  I recommend turns of reasonable diameter that satisfy that. 
Above about 15 MHz, turns should  spaced widely apart except where they 
go through the core. See the text, measured data, and photos.
