Stragegy for 2-sided milling of a sphere

[gj101]

Hello - 

I am attempting to mill a perfect (dare I say!)  sphere using two-sided techniques on a block of wood. After some 3d adaptive clearing, is it better to use the scallop toolpath or parallel for this project? Thanks.

Scallop will work, as would Contour or Flow. You will need to split the surface in half for Flow to work
