I am pretty sure I have both. My 101 with the Mean V on it was quiet even shooting my 325 grain 3D arrows. They were flying at 324 fps at 59 pounds. Ya, 59 lbs. Now I am shooting a 440 grain arrow at 63lbs. I haven't chrono'd yet, but it should be around 300 I think and it is even more silent. Either way I love this setup.
