ZBrush: Twist Deformation creates bad topology

Hi,

So I have this problem in Zbrush when using Deformation-Twist:


As you can see It creates some nasty geo where its been twisted. I guess thats to be expected! I can't figure out how to sort it out, dyna mesh and zre-mesher crash when i try them (maybe the geo is too twisted?). But perhaps I shouldn't be doing it this way in the first place.

I'm trying to create a pillar with this pattern on it:


I thought the best way would be to mask an area, use radial brush and draw those lines/grooves straight down. Then mask an area a little further down and twist it. But that ends up bad.
Is there a better way to model that pattern? How would you go about it?

    I'd delete the portion where the twist error is.

    If the geometry lines up perfectly with the straight grooves then you can bridge the two parts together (use the curvebridge brush, zmodeler brush, or do it externally). 

    If they don't line up, I'd probably delete the entire top half and then extrude the edge of the twist upwards to create the straight grooves. If you do this in zbrush then you'll need to cap the holes first as zmodeler prefers to work with closed volumes and will do some funky stuff when confronted with open edges. Use the zmodeler brush ("Close" edge action) to close the holes, NOT the Tool: Geometry:Close Holes; the latter result will be absolute garbage.
