Toko riller bar question

Hi,

The Toko riller that comes with two bars comes with the following
description:

Toko Nordic Structurite 2 Riller
Same as the Toko Nordic Structurite 4 Riller but with only two rill bars.
Comes with one coarse transverse/broken bar and one fine transverse/broken
bar.

Question: Is the fine transverse/broken bar the best for cold conditions?
Or is it a straight fine linear bar?

(Here's the description of the bars in the 4 bar riller from Toko: The four
bars a coarse linear, fine linear, coarse transverse/broken and fine
transverse/broken. The linear bars make straight rills (good for reducing
excess water film) while the transverse make a "broken" pattern (good for
breaking suction). Use the fine bar structures when the snow structure is
well defined (i.e. cold, fresh snow), and the coarse bar structures when the
snow structure is aged or soft (i.e. corn snow). )

Thanks,

Brian
