In respect to some older members (Like yourself, Arachne ) I haven’t being around on Club MyCE long enough to know in detail about cake boxes, but I can tell the difference between a Jaffa Cake and a Battenburg!
On a serious note though, the experience I have got from Club MyCE about disc burning speeds, brands, dyes, etc is head spinning, but very fulfilling. I think since I burned my CMC discs on the Pioneer burner I unfairly called them Godawful discs, like RiDisc, etc. But I think these discs would have been okay, had I not burned them on the Pioneer burner. Since moving up to a BenQ burner or even the trusted Phillips, I have had consistently excellent performance on CMC MAG discs.
However, I’m not lured by CMC MAG anymore, and I made it a rule of thumb for everyday discs the RitekF1 is a far more stable dye. Gee, you think for me bloating threads trying to plug the Ritek dye I actually work for Ritek, hahaha!
The second lesson I learned is for DL media, the only reliable (and one to make it after the layer break) Verbatim, nothing else. And for me using -RW under any brand is something I personally avoid - Issues with writing over them, etc.
