: Upon checking their site, I discoved that Klingspor offer four different
: types of disks in the size and hole configuration I need (5", 8 hole,
: Kling-On). They are lightweight paper, lightweight stearate paper, heavy
: stearate paper, and heavy paper. Based on their descriptions, it seems
: like the heavy paper disks are the most durable. Which is the best way to
: go?

I go with the light sterate discs. At the price they sell them for, you can afford to burn through them, especially when sanding glass/epoxy. I also agree that these are a great deal. Sure better than the over priced stuff at the local hardware store! I think the last time I bought, they were about $14 for a box of 100.
