    Making progress 165 fps 412 gn 24.9 ft pounds.

    My xbow Black TB just shot at its best.

    I keep shortening the relaxed length of Theraband.

    It went from 95,110, 127, to 165 fps as I shortened the rubber.

    It uses double Black per side 6" pulled to 24".

    I am satisfied with the speed.

    My next goal is to increase the arrow weight to 750 gn.
