The LTH media uses an organic dye recording layer similar to that of a CD-R or DVD-R/+R. These are fine if you really don't care about longevity, but for archiving, normal BD media is better.
JVC/TY is the only BD media I haven't tried at this point. As long as you still to a name brand, you're good. I've had good results with Sony, TDK and Verbatim. Keep in mind though, if you want to write at 14x with that drive, you will need Sony or Panasonic discs.
