Where are you located? Zip code works best.

1. My zip code is in the original message.

2. My zip code is irrelevant to the question. Anyway, I did some more research myself, and the general consensus out there, both from scientific studies and personal experimentation, is that RTF is a sham.

Location is almost never irrelevant to lawn questions. You might think it was in this case, but I suspect auteck had another angle he was thinking.

Thanks for doing the extra research. I've just now heard of the RTF fescues, so it's good to know what they are and are not.

Yes, I find the issue of RTF very interesting because I actually found a scientific study that concluded that RTF does not form rhizomes anymore than regular TTTF. (I also learned from reading that study that TTTF actually does produce some short rhizomes in very small numbers.) The blogger's experiment was also very well done and showed no spread from the RTF. Yet the claims persist in full force.
