I have used a biscuit and loved it. I went to a rip cord because my new DXT was a bear to tune with the biscuit, too tight of tolerances. Yes many use a biscuit on the DXT and are successful, not me. A DXT with a biscuit and blazer vanes I could not make work, and got frustrated and went to the rip cord. I really do like the rip cord, never had a problem, and it works flawlessly. I was using the biscuit on a Jennings Grandmaster and stuck the biggest buck I have ever shot. The DXT shelf hit my vanes every time with a biscuit and blazers no matter how I turned the vanes.
