What’s wrong with the TDK TTH02? I bet everyone here who doesn’t even consider them and just recommend the TY have never used any of these TDK discs. I happen to like them 
TTH02, assuming it’s TDK branded, is very good in most recent burners and does well in accelerated aging tests.
I like TY as much as the next CDFreak, but disregarding a good media just because it’s neither TY nor MCC, this sounds strange to me. 
Also unbranded TY can be bought from SVP only in 100-discs spindles, and these are far more fragile during transport due to the weight/resistance ratio. I had several broken spindles of these.
- now I buy DVDRs only in 25-discs and 50-discs spindles.
@ the original poster:
TDK-branded TTH02 burn very well in my 109. It’s just as good a choice as TY in my opinion. Like all 16X rated media, better burn them @12X.
Anyway, if there’s any trouble with these discs (which I doubt), SVP will replace them 
If you want 16X Verbs, IMO better go for the +R MCC004 (less variation in quality). But I guess you want -R because the 109 doesn’t support bitsetting…?
Unbranded TYG02 is among the most reliable media around and burns very well in my 109. TY discs from SVP are 100% genuine.
