Thoughts on the Micro-Swiss cooling block?

[MichaelStolworthy]

Does anybody have the Micro Swiss cooling block or have any thoughts of using it in conjunction with the ZT-HE?

I don't see any big reason why the Micro-Swiss heatsink would be better than the stock one, apart from the way it clamps around the hot end feed tube, perhaps providing better thermal contact than the Zortrax grub screw. I've played around with heat sink compound at that point and not noticed much if any difference.
