Datawrite Grey discs & RitekG05

[Pacis]

Can you please tell me what do you think about these discs?

DATAWRITE GREY 8X (Media Code: FUJIFILM03) -R
DATAWRITE GREY 8X (Media Code: PRODISK R02) +R
I think the Fuji is good, isn't it? I have not heard anything about the R02.

And about these two:

DATAWRITE 4X (Media Code: RITEKG05)
RIDISK 4X (Media Code: RITEK G05)
Can these really be burned at 8x (with good quality), despite saying that is 4x (as they are ritekg05) ?

Thanks for your help.

The Fuji 03 dye is a good one, or at least has been for me but seems to no longer be avaiable here in the uk. The datawrite greys 8x here now seem to be either a new fuji dye or a prodisk dye depending on where you source them from. Svp or UkDvdr
I was under the impression that the Ritek G05 dyd was a 8x dye. Could it be a typo on their site ?

Thanks for your reply.
As a matter of fact, they are RitekG05 and have 4x in the label. So, will they burn at 8x, once they are ritekg05?

Once again, what do you think about these two discs?

DATAWRITE GREY 8X (Media Code: FUJIFILM03) -R
DATAWRITE GREY 8X (Media Code: PRODISK R02) +R
I have not heard anything about the R02.
Thanks

DATAWRITE GREY 8X (Media Code: FUJIFILM03) -R
Are great have used 300+ with no issues. If you know of a source please post a link as i could do with some more. As for the +R Datawrite i have no idea as i only use -R here.
Only way to find out if the Go5 will burn at 8x is to try one. Could be a typo, but untill you try one its hard to say.
