They will out last most other stones that are three times the thickness. These abrasives are extremely uniform. Consistency is the primary goal for Shapton's engineers. The abrasive that you encounter with the first pass will be the same on the 5,000th pass. And, this will be true for every every abrasive size.
Apparently in shapton glass math, (5mm glass) =/> (15mm anything else)!
Not to mention the price: 130 for the shapton 15k vs 99 for the glass 16k,
and 635 for the pro 30k vs 280 for the glass 30k. (prices in MSRP)
If you leave out the 220, 3000, and 6000 stones, you can buy the entire shapton glass series for about the same price as the pro 30k. That's a lot of pudding.
