Wow, it said MIJ but was Ritek? Man, buyer beware, I guess. Haven't come across one myself, but Ritek is known to vary in batches quite a bit. I've gone through two spindles of R03, one which was exceptional quality and burnt with a PIE max of 20, and another which burnt with a max around 100. Big difference!
Because of this, we can't really say if they're better or worse than Traxdata, since maybe one spindle of Traxdata is a good batch, another is bad, one spindle of this is good, another is bad... etc etc.
Oh, and it's Maxell. (Sorry, big pet peeve)
