Shapton Pro vs Glass Stones

So a couple weeks ago I picked up a couple Shapton stones. When I bought them, they were advertised as the Shapton Glass stones... turns out they're the Pro stones instead. What is the real difference in them, other than obviously one is mounted on glass and the other isn't. I'm a bit compulsive on making my stuff match (unless I can find a good reason not to) so I'm trying to do the research to decide if there is a good reason to go with one over the other. I've never set eyes on a Shapton Glass, but they look to be thinner than the Pro. Is this the case?
 
This comes down to personal preference. I agonized over the differences for quite a while and finally settled on the pros. They are awesome and I was immediately able to get respectable results. I have 1k, 2k, 5k, 8k & 15k pro stones and I am quite pleased with them. I opted for a Seuhiro 20K rather than the 30K Shapton as a super finisher. As far as the glass stones, I only know what I could find on the webs and nothing tells me they are any better or worse than the pros. Hope this helps.
 
Yes - the Gs series is thinner than the Pros. There are, or at least were, two different series in the GS line. One was harder and each were supposed to be 'better' for certain steels/applications.
I have two Pros, good stones. I don't have any of the GS stones but people like them too.
I suppose you can't go wrong with either set. Try one from the GS series - see if you like it.
Thats the only way to know for sure.
I'd guess that it's more of a "six of one, half dozen of the other" thing though.

I have a set of glass stones but have not used any of the pro stones. The glass stones are thinner, 5mm of abrasive on a 5mm thick piece of glass while the pros are 15mm thick. They are hard and slow to lap and I cannot imagine wearing one of these out. There are rumors that the glass stones are a newer technology and that the pro stones are being phased out, but I have no idea if there is any basis for this.

I have several Shaptons. The GlassStones look very insubstantial at 5mm thick, but I haven't been able to wear them out in six plus years of fairly regular use on knives, so I would think they'd last a lifetime on razors unless you're honing for a living. The Pro series was their top of the line for a long time, but they're really just like their old M15 series with increased cutting material and no wooden board attached to them. Not much in the way of feedback, but all of them are very nice stones that cut quickly.

An odd but useful advantage of the GlassStones is that the glass side makes for a wonderful base for sharpening films. :lol:
 
I've owned both and I prefer the Pro's. I get much more feedback off them than the glass stones. I also found that the Pro series cut a fair bit faster than the glass stones.
 
Got it. Thanks. One last question... Do the Glass series come in or with cases like the Pros do?

That was actually one of the deciding factors for me. The prices were comparable between the glass & pros, but the extra bucks for a holder to keep it up off the table was not attractive to me. I was unable to find any kind of consensus in any forum or online reviews that one was really any better than the other, so I went with the pros and I'm very happy with them.
