In what regard?  Yes, lower loss, but from a dissipation point of view 
it doesn't matter.  Do the arithmetic to find the current. What matters 
a lot more are issues like common mode impedance as a function of 
frequency and the Zo of the line, both of which depend on the conductor 
size and spacing.  18 bifilar turns (18x2) is about the practical limit 
on a i.4-in i.d. core, and 16 isn't easy.
