In my experience with TDK-branded inket printable TTG02, they are very variable in quality.
For example, my friend has a spindle that is near perfect, the stuff scans nearly as well as Taiyo Yuden. My spindle, on the other hand can be anywhere from very good to horrible, depending on the disc in the spindle. It is not rare for PIE to go up 10X and PIF go up 5X from one disc to the next, in the same spindle! I have even had discs with enormous, unreadable PIF mountains.
My advice to you is the scan every disc you burn, if you have a scanning drive, and if not run a transfer rate test in Nero CD Speed.
FYI: this is based only on my limited experience with CMC-manufactured TTG02!
