Anyone use GreenKut OR Alumina-Zirconia paper for Drum Sander

[Curtis Myers]

Anyone try the GreenKut or Alumina-Zirconia sand paper for their Drum Sander?
Both clam to last much long then Aluminum Oxide paper. Anyone with experience using these Drum Sander paper?

GreenKut from Keystone Abrasives
GreenKut is a NEW ceramic grain coated abrasive material designed specifically for wood working applications, with an open coat. In many cases, GreenKut can provide 5-10 times the life over standard aluminum oxide when sanding wood.

Alumina-Zirconia from Klingspor
Tough Alumina-Zirconia grain that are resin bonded to a heavy weight cloth backing make for an abrasive that will outstand and outlast any other abrasive on the market. It also tends to run a little cooler than typical abrasives, which makes it load less, making it ideal for tough drum sander applications.

Last time I was ordering rolls for my drum sander I went with the Zirconia ones (blue) and I think they do last longer than the aluminum-oxide paper.
They are a little more money but seem to last longer as well.

The cost is almost twice what I pay for my drum sander paper.

I order zirconia where possible -- it does seem to last longer.
