Curious-- How do you define "fast" in actual fps vs other limb types fps expectations?FWIW, I shoot a ILF Recurve with Carbon limbs....not because they are carbon...but because they are quiet, low vibration and fast.
Carbon fiber looks fast in the parking lot, and cars with a lot of torque seem fast to the butt-o-meter but actual horsepower to ground and timeslips win.
