Planar Curve

Hi All,

I'm having problems with the Explode component of grasshopper. I have a curve that I want to be exploded into Arc-like Curves and into Line-like Curves. But for some reason there are also Planar Curves between them. Now that would't be a problem if these Planar Curves where as Arc-like Curves or as Line-like Curves. But the Planar Curves in my list sometimes are like Arc-like Curves and sometimes like Line-like Curves. 

Well that are a lot of curves.... Is it possible to avoid the Planar Curves and only have a outcome with Arc-like Curves and Line-like Curves?

Thanx!
