Hello there and welcome to the Yard. The TT did have differences between the release Reg/Derg. As noted the choil, saber grind and non-diff heat-treat for the release Reg/Dereg. Enjoy your new blades, grab a LE and a release Regulator if you can while the prices are right.
Thanks for the replies. What does non-diff heat-treat mean? What does that mean performance wise?
